I don't see how Carol is to blame for anyone's death

His mother and father should have better prepared him for what was outside the walls and Rick and Jessie should have forced him to go with Gabriel to the church.

If anything Carol was the only one who warned him of the true danger of the walkers, could she have been nicer? yeah but it's not exactly a nice situation and actually a lot of her warning to him ended up being true.

Also she shot the Wolf dude because as far as she was aware he had taken Denise to kill her like he and his kind had the innocent Alexandrias not long before.
