John Chrysostom
Patristic
A.D. 347–407
“Man, through malice and wickedness, that is, by his own will and the effect of wrongful action, kills the soul. Therefore someone has said: no one can be harmed except by himself, because he is either the originator of his own crime or consents to the crimes of others. For if a man guards his mind and does not consent to evil persuasion, he is free from all guilt.”
