Is Charlie dumb?

In season 2 she is freaking out about how sinners become reddemed and tbh the whole episode or 2 on this seems dumb because its in the name. How i see the rules of redemption is 1. You have to do the opposite of your major sin (sir pentious is too cowardly to do anything and is redeemed by taking command of the situation) 2. The sinner needs to die and not have their soul owned by anyother sinner. As far as things go these are the 2 rules.

I can understand her not knowing the 2nd rule but it seems dumb she cant work out the 1st considering she likely knows about sir pentious's sins.

Whats your guys,s thoughts?
