Sure, but be aware that they might fight to the death to prevent you from taking that which permits them to sin.

You can't make them save themselves. If you press to hard, they may kill themselves, or you, when confronted with a reality where they can no longer sin.

In such cases, God says to dust your feet off and leave them be.

However, if they force you to accept them then you can't just ignore them.

If you can't ignore them, and you can't convince them, and they are threatening your own salvation, then what is left for you to do? Let them?

They may take your life, but when they try to take your soul, the only option is to fight back, and not play Mr. Nice Guy anymore. They become Satan, which means Adversary.

Universe -> One Verse -> One Word -> The Word

Satan -> Adversary -> Against the Verse -> Against The Word

The ultimate evil is the rationale that the ends justify the means.

If you attempt to save another, but in turn you corrupt your self by participating in their evils, then such a foolish ambition itself is evil.

I hope I'm making sense.

Ultimately, you can't save them all.
