It... depends on the action that has been made. If it's something like cheating on me, then you're dead to me. Normally I would give a second chance.

Yes, I’ll give a chance while promising to change for the better.

Depends on whom and what.
Tho I will not put 100% trust for sure.

I think it depends but usually no.

Depends on what kind of problem I’m currently dealing, but I usually do.

There are things that are unforgivable by nature, it's an irreparable harm. But for most of the time, I'll give them a second chance. After all, those who repent will be forgiven, but not forgotten. 

some people deserve a second chance; it depends on what they did to me. if they made me way too disappointed, then it’s a no from me.

I've dealt with this kind of thing. So, my answer is gonna be no and yes. No if I didn't love you badly, yes if myself is fell so badly to you. Depends on whom.
