“But evil is a cunning force. It can find the weakness in any man, even the bravest. [...] It only takes a single weak moment to let evil in.”
“There is no good and evil, there is only power and those too weak to seek it.”
“Weakness begets evil”
“People are rarely diabolic or bent enthusiastically on evil. As a rule, they are only weak; they cannot resist temptation and thus give way to their evil drives.”
“Humanity is not perfect in any fashion; no more in the case of evil than in that of good. The criminal has his virtues, just as the honest man has his weaknesses.”
“Weakness is a contagion, one breath of it can corrupt a man whole and entire. Now though, even with all the evil in me, I don't know if I could teach such lessons to a son of mine.”
