My god, you've found the answer! Now let's have one for,
if someone is alive, don't murder them
if you see something don't steal it
and it's the end to crime!

I don't mean to trivialise the issue, but how does this help?
Whilst obviously there are extremes, everyone has to take some care in looking after themselves.
In any society, there will always be scum. It doesn't matter what you say or do, one day you may run into that scum.
