Restraint from unwholesome actions is a virtue in Buddhism; such
virtue leads to non-remorse, to gladness, to happiness, to
tranquillity and joy(sukha, happiness) that is the requisite for
concentration (samadhi). Beyond concentration is higher mental
purification and higher understanding (adhipaññaa). Direct knowledge
is a kind of higher understanding. The process of purification
(trainings) in virtue, concentration and understanding is beautifully
described in the "Path of Discrimination" (Patisambhidamagga) by the
great Arahant Sariputta as follows.
[Ref. Page 47. The Path of Discrimination. Translated from the Pali by
Bhikkhu Nanamoli. Published by The Pali Text Society, Oxford, 2002.]
265. "In the case of killing living things abandoning is virtue,
abstention is virtue, volition is virtue, restraint is virtue, non-
transgression is virtue. Such virtues lead to non-remorse cognizance,
to gladness, to happiness, to tranquillity, to joy, to repetition, to
development, to making much of, to embellishment, to the requisite
[for concentration], to the equipment [of concentration], to
perfection, to complete dispassion, to fading away of greed, to
cessation, to peace, to direct knowledge, to enlightenment, to
Nibbana: the purification consisting in restraint in such virtues is
the higher virtue. Cognizance established in the purification
consisting in restraint does not become distracted; the purification
consisting in non-distraction is the higher cognizance. He sees the
purification consisting in restraint correctly, and he sees the
purification in non-distraction correctly; the purification consisting
in seeing is the higher understanding.
"The meaning of restraint therein is training in the higher
virtue, the meaning of non-distraction therein is is training in
higher cognizance, the meaning of seeing therein is training in the
higher understanding.
"He trains by adverting to these three kinds of training[adhi-
sikkhaa], he trains by knowing them, by seeing them, by reviewing
them, by steadying [cognizance] upon them, by resolving with faith
upon them, by exerting energy upon them, by establishing mindfulness
upon them, by concentrating cognizance upon them, by understanding
them with understanding, by directly knowing what is to be directly
known, by fully understanding what is to be fully understood, by
abandoning what is to be abandoned, by realizing what is to be
realized, he trains by developing what should be developed." [end of
excerpt]
Killing (taking life) is just one of the ten unwholesome actions,
namely : Killing, taking what is not given, sexual misconduct, false
speech, malicious speech, harsh speech, gossip(foolish babble),
covetousness (also, selfishness), ill-will, and wrong views. For each
of the ten unwholesome actions virtue is in the sense of its restraint
and its non-transgression. [The above paragraphs are to be repeated
for each of the other nine unwholesome actions.]

Best wishes.
Talking about training (sikkha) for higher understanding, someone may be curious about how it might be done. The following Sutta shows that wisdom or pa~n~naa does not arise in isolation from the trainings in higher virtues and higher mind. Direct knowing is one of supporting conditions (paccaya) for the three higher trainings.
Kassakasutta.m
84. Bhikkhus, these three activities should be done earlier by the farmer. What three?
"Here bhikkhus, the farmer should first prepare the field, then harrow it well carefully and embed the seeds at the right time. At the right time he should lead the water in and at the right time lead it out. Bhikkhus, these three are the activities that should be done earlier by the farmer.
"Bhikkhus, in the same manner these three activities should be done earlier by the bhikkhu. What three? Training in the higher virtues, training the mind to a higher degree and training for higher wisdom. Bhikkhus, these three are the activities of a recluse. Therefore bhikkhus, you should train thus: Our interest will be keen for training in the higher virtues, for training the mind to a higher degree and for a higher training in wisdom."

The dhammas that support (as condition: paccaya) for the three higher trainings are adverting, knowing, seeing, reviewing, steadying the mind, resolving with faith, exerting with energy, establishing mindfulness, concentrating the mind (unifying it), understanding with pa~n~na(discern, pajaanaati), directly knowing, full understanding, abandoning, developing (bhaavana), and realizing.
