For some people, there will be no good answer.

For some behavior, there will be no good reason.

For some things, there is no good explanation.

For some are just wrong, just bad, just inexcusable.

Stop trying to justify the evil.

Stop attempting to rationalize the nefarious acts.

In your explication, enablement is all that can be found.

Woe to those who call evil good, and good evil; who put darkness for light, and light for darkness; who put bitter for sweet, and sweet for bitter! Woe to those who are wise in their own eyes, and prudent in their own sight!

Isaiah 5:20-21
