2a. from Bhikkhu Bodhi's http://www.accesstoinsight.org/lib/auth ... ay_36.html
http://www.accesstoinsight.org/tipitaka ... .than.html defined, this is a reference to Buddha's Words.To dispel any doubt about his reasons for prescribing this precept, the Buddha has written the explanation into the rule itself: one is to refrain from the use of intoxicating drinks and drugs because they are the cause of heedlessness (pamada). Heedlessness means moral recklessness, disregard for the bounds between right and wrong.
Also same explaination found in the AN 4.99 Sikkha Sutta: Trainings
3a. People are most welcome to present evidence for the not being able to break any of the 5 precepts, i could not find any for the 2,3,4 and 5th. Furthermore if he does not kill or wishes others to kill that is an unbroken virtue it itself, which would be dear to the Noble Ones.
4a. Unwavering confidence In The Triple Jewel and the virtues dear to the noble ones—unbroken, untorn, unblemished, unmottled, freeing, praised by the wise, ungrasped, leading to concentration. (anybody claiming this refers to never breaking the 5 precepts needs to produce evidence)
5a. Also be related to 3a
6a. Referred to as Panca Sila, https://suttacentral.net/en/sn12.41 also related to Five faultless gifts (http://www.accesstoinsight.org/ptf/dham ... asila.html ) http://www.accesstoinsight.org/tipitaka ... .than.html) & are seemingly related to Five Fearful Animosities https://suttacentral.net/en/sn12.41
1b. "Subsides" should be straight forward, i assume the Pali isnt tricky here. https://suttacentral.net/en/sn12.41
2b. Following passage should be illustrative of importance of Concentration in regards to abandoning Ill-will and Sensual Desire
Relevant on Sotapanna:MN 14 wrote:"Even though a disciple of the noble ones has clearly seen as it actually is with right discernment that sensuality is of much stress, much despair, & greater drawbacks, still — if he has not attained a rapture & pleasure apart from sensuality, apart from unskillful mental qualities, or something more peaceful than that — he can be tempted by sensuality.
Dhammapada Story v.124"Bhikkhus, the sotapannas do not kill, they do not wish others to get killed.
Here is Buddha's Word. Also noteworthy quote in regards to suicide because the Buddha says "others", but this is offtopic.
Clearly heedlesness is a problem."And what is the individual who is a bodily witness?... I say that he has a task to do with heedfulness. ...
"And what is the individual attained to view? ... I say that he has a task to do with heedfulness. ...
"And what is the individual released through conviction? .... I say that he has a task to do with heedfulness.
So he does offenses that need confession fwiw.MN 48. http://tipitaka.wikia.com/wiki/Kosambiya_Sutta "Bhikkhus, what is that unique characteristic of one come to righteousness or view? When he does any wrong, it becomes manifest to him, and he instantly goes to the Teacher or a wise co-associate in the holy life and declares and makes it manifest and makes amends for future restrain, like a toddler who is slow to stand and lie would tred on a burning piece of charcoal and would instantly pull away from it
The words exceedingly heedless are interesting in the context of discussion.Ratana Sutta... 9. ... even though they may be exceedingly heedless, they will not take an eighth existence (in the realm of sense spheres).[6] This precious jewel is the Sangha. By this (asseveration of the) truth may there be happiness
... 11. "Any evil action he may still do by deed, word or thought, he is incapable of concealing it; since it has been proclaimed that such concealing is impossible for one who has seen the Path (of Nibbana).[8] This precious jewel is the Sangha. By this (asseveration of the) truth may there be happiness.
Sumanā obtained the Second Fruit of the Path, but remained unmarried. Overwhelmed with disappointment because of her failure in finding a husband, she refused to eat and died and was reborn in Tusita (DhA.i.128f)
He is also fully freed from the four states of woe, and therefore, incapable of committing the six major wrongdoings.
Abhithanani; i. matricide, ii. patricide, iii. the murder of arahants (the Consummate Ones), iv. the shedding of the Buddha's blood, v. causing schism in the Sangha, and vi. pernicious false beliefs (niyata micca ditthi).
Some people say that he cant break 5 precepts because 5 precepts are said to lead to hell, however i think this is rather naive and is rebuked by the Sutta called "Who Took To Drink" and other instances:Bahudhatuka Sutta MN. 115 Quote: “He understands: ‘It is impossible, it cannot happen that a person possessing right view could deprive his mother of life ― there is no such possibility.’
Here bolded part describing Non Enlightened desciples:
Visudhimagga:"Take the case of another man. He is not even endowed with unwavering devotion to the Buddha, the Dhamma, the Sangha. He is not joyous and swift in wisdom and has not gained release. But perhaps he has these things: the faculty of faith, of energy, of mindfulness, of concentration, of wisdom. And the things proclaimed by the Tathaagata are moderately approved by him with insight. That man does not go to the realm of hungry ghosts, to the downfall, to the evil way, to states of woe.
"Take the case of another man. He is not even endowed with unwavering devotion to the Buddha, the Dhamma, the Sangha. He is not joyous and swift in wisdom and has not gained release. But he has just these things: the faculty of faith, of energy, of mindfulness, of concentration, of wisdom. Yet if he has merely faith, merely affection for the Tathaagata, that man, too, does not go to... states of woe.[7]
"Why, Mahaanaama, if these great sal trees could distinguish what is well spoken from what is ill spoken, I would proclaim these great sal trees to be Stream-Winners... bound for enlightenment, how much more so then Sarakaani the Sakyan!
Strangely no mention of The Second Path nor is it specified which wrong action is abandoned. In any way it is the most support one will find for a Sotapanna Lay or Monastic being unable to break 5 precepts and this is not explicit nor is this in the Tipitaka.Visuddhimagga: In the case of the wrongnesses, wrong view, false speech, wrong action, and
wrong [685] livelihood are eliminated by the first knowledge. Wrong thinking,
malicious speech, and harsh speech are eliminated by the third knowledge.
And here only volition is to be understood as speech. Gossip, wrong effort,
wrong mindfulness, wrong concentration, wrong deliverance, and wrong
knowledge are eliminated by the fourth knowledge.

Conclusion:
As i see it, Not being able to break any of the Five theory doesnt have much foothold and furthermore is imo an evil view which doesn't go well with the Sutta Pitaka.
Why is it evil?
Because it opens up for denouncing them because their virtue does not seem Holy enough, denying their Attainment.
If one held view that It is possible for them to break #2,3,4&5 then it is not as big of adeal because that would not lead to saying "You dont have the Attainment" even if one was wrong in his view.
