You find the right argument but you failed to make the right conclusion.
Running a red light you are intentionally putting others lives at risk. If you run a red light on accident and you kill someone, it's manslaughter. If you intentionally run a red light and kill someone its murder 2.
Your inability to understand that killing someone when you run a red light and hit them is either man slaughter or murder is probably where your inability to see how your position is flawed comes from.
