Does against the law= bad?
My great grandfather died in Siberia for "breaking the law"
It's not exactly a black and white answer. Breaking the law is ... against the law. And you could be punished for it.
I don't know how others look at it but there are plenty of things people do that are breaking the law that I don't specifically have a problem with.
If my loved ones were dying and needed an organ and I could buy one against the law on the black market, would I do it?
If someone goes, and kills someone who tortured and killed their loved one, do I hold it against him?
There are plenty of things that are against the law that I don't think are "bad". And there are various degrees of it too. Even the above two examples aren't the same.
I don't believe (not halachically, or personally) that people should take the law into their own hands when dealing with a "bad guy".
On the other hand I wouldn't have a problem buying an organ to save someone's life.
