Of course there's a meaningful comparison! It may not be 1-to-1, but if per-capita the US has equal crime but double the fatal crime, it's a red flag that should at least direct our attention.
It's obvious that firearms are an escalating force. Their presence creates a scenario where a criminal now has to very quickly decide between dying, killing, calling the bluff, or fleeing. It can make a non-fatal crime fatal.
There are questions like "are firearms even effective for self defense?" Or "do firearms save fewer people than the number of conflicts escalated to fatality?" If most women won't pull the trigger, is it an equalizing force or does it give the criminal a more fatal weapon to wield.
All the discussions I see on firearms are so surface-level and generally lack the level of intellectual curiosity I think the topic requires to properly discuss whether or not the second amendment was a good inclusion. And that's before you get into the (IMO nonsense) discussion of "overthrowing the modern government".
I'm not equipped to have this discussion, to be clear, it's far too nuanced and requires numbers I don't know. I would need to rely on dedicated researchers.
