Your point is based on an event that he was in jail for 5 years.

Correct?

What I'm saying is with Kate's law he would of gotten more than 5 years. He could of kill some other person but Kate would of not died that day.

You said Kate's death would not be save by that law, and I'm telling you are wrong. The right statement is that law cannot guarantee that no deaths will happen.

Please tell me you understand it.
