I’m afraid these isolated, out-of-context sentences don’t make much sense to me. Still, I’ve tried to do my best.

Younger infants are prone to bear little malice towards anyone around them, even when they encounter (a slain porter??)

The attitude of (holding coronation to foe??) is a way of treachery and it is also liable to death penalty.

You are a guy prone to bear others hate and prone to pay back subordinates’ treachery.
