Your logic appears to be that

"Some people violate the law and use illegal X to commit terrible crimes.
If we get rid of the legal X, there will be less crime:
Nobody should have X."


I disagree with the logic you offer- Consider- If we castrate all the non-sex offenders, will that have any effect on the rate of sex crimes?
And is the cost worth it?

As I have said, several times,

Is the goal to reduce deaths, or limit the ownership of firearms? I do NOT consider that these are the same point.

I have pointed out info that supports the fact that citizens legally HAVING guns can serve to reduce the killings. IMO, prohibiting legal gun ownership will result in a LARGER NUMBER of killings by illegal guns. Nothing you have presented has addressed this. Nor have you addressed how you can SIGNIFICANTLY reduce the number of guns available. I am sure the people of Fergusson will be thrilled to turn over all their weapons to the police. That was what the Jim Crow laws tried to do, and they did not succeed.
