Murder is wrong because it violates an individual's rights.
Rape is wrong because it violates an individual's rights.
"Gun control" is wrong because it violates an individual's rights.
There is really no difference in the wrongness of those wrongs.
These things aren't wrong because they are illegal and aren't right when they are "legal".
They aren't wrong because people agree they are wrong.
They don't stop being wrong if a majority stops believing they are wrong, because individuals are still being violated.
If an act violates the rights of an individual, then you have no right to do it. If you do it anyway, you did wrong. You committed evil. That you believe your act is "necessary" changes nothing.
