Ariyans cannot perform acts of evil. That is why they are called 'Ariyans'. The suttas say:
"And which are the four factors of stream-entry with which he is
endowed?
"There is the case where the disciple of the noble ones is endowed
with verified confidence in the Awakened One: 'Indeed, the Blessed One
is worthy & rightly self-awakened, consummate in knowledge & conduct,
well-gone, an expert with regard to the world, unexcelled as a trainer
for those people fit to be tamed, the Teacher of divine & human
beings, awakened, blessed.'
"He is endowed with verified confidence in the Dhamma: 'The Dhamma is
well-expounded by the Blessed One, to be seen here & now, timeless,
inviting verification, pertinent, to be realized by the wise for
themselves.'
"He is endowed with verified confidence in the Sangha: 'The Sangha of
the Blessed One's disciples who have practiced well... who have
practiced straight-forwardly... who have practiced methodically... who
have practiced masterfully — in other words, the four pairs, the eight
individuals — they are the Sangha of the Blessed One's disciples:
worthy of gifts, worthy of hospitality, worthy of offerings, worthy of
respect, the incomparable field of merit for the world.'
"He is endowed with virtues that are appealing to the noble ones:
untorn, unbroken, unspotted, unsplattered, liberating, praised by the
wise, untarnished, leading to concentration.
"These are the four factors of stream-entry with which he is endowed.
