You are assuming gun homicides are done by people purely intent on death. Death rates from crimes will change drastically if you remove guns from the crime.
And i'd say it depends on the right. What if the constitution stated everyone should have the right to drive thru stop signs? I'd say that right should be infringed upon if it meant fewer tragedies. It's a trade-off for being in a civil society.
good luck taking guns away from people who demonstrably have no regard for the law, particularly laws that say they can't have guns..
The regulation of stop signs is done locally as part of regulating all traffic. You have a right to drive within those regulations. Same with guns. It isn't like the Constitution says guns have to be free of regulation. There are regulations that cover gun use just as there are with stop signs. I think your analogy is not a good one.
