According to the law pov it's wrong. But when i place myself in his shoes...maybe i would have done the same if i think from an avg human pov

There is definitely a big difference between objective law, and the emotions a human being goes through.

While I imagine I'd probably want to kill someone just as much if they laid a hand on a young family member of mine, I do think the law has it's place.

What does killing the pedo really achieve?

I don't know how well-received this opinion will be, but I personally believe it would be good for psychologists and medical professionals to study pedos as much as possible, rather than handing out death sentences. It would be good if they can find out why human beings turn and exhibit the thoughts and behaviours pedos do, with the intent to preventing instances like this re-occurring. AKA, solve the root cause of the problem.
