This is a really hard one.

Because there are people who are irredeemable.

Narcissists / Psychopaths who do not have any empathy.
They view people as you would view your TV set.
And dispose of them just as easily when it stops being beneficial.

Still, i can care about these people's souls, but i can't allow them to live and influence my world.

We often talk about pedophila being the worst.
Then you have child trafficking, rape and murder.

And then you have people who think it is best if the world only had 500 million people.
