It's of topic but, what if our current civilization is failing them? Like, of the system is broken and an individual acts to protect themselves or their family, the individual is still blamed.

That's how revolution starts.

And there are many revolutions that we (in USA) claim are good! Our own, from Britain, the French one. Of course others are bad (depending on where your vantage)

It's just that, sometimes the murder is (retrospectively) justified. Like in a war, they're killing us so we kill them.

But class war isn't fought with uniformed combatants.

And, in USA at least, many of our politicians are bought quite blatantly. If they aren't serving the citizens perhaps they have thrown out civilization and the social contracts first?

It's all quite complicated.

In general though, murder bad and government should serve the poorest citizens forst, corporations last.
