Part of the sin of presumption is thinking God must forgive you even if you don’t repent, no matter how big of a jerk you are.

So who thinks that happens, that God has to forgive us without repentance?

So who thinks that happens...

It would, by definition include those who rely on, or presume, pardon of his/her sins without repenting of them. This can also include Catholics of course.

I don't think this a null set. I think could also include those who believe all their sins (past, present and future) are already forgiven. And there could be some overlap logically with those holding to OSAS belief.
