The thing is that tons of strangers are celebrating his death and they know nothing about him bar a job title and a ton of misinfo. So if I were a kid I wouldn't think I'll of my father I'd just think worse of the general pop.

I'm a Brit, but this film pissed me off no end, purely for the inhumane suffering and death caused by Thompson and his ilk. Every single one of them should burn in hell.
If there is i haven't seen it. I don't know why you feel the need to defend them. Even if it's overstated it's still thousands of preventable deaths a year at the very least.
