In the song, the lyrics speak of someone blowing someone else away by putting a loaded shotgun in their mouth and pulling the trigger, because they committed criminal trespass of the type that would usually result only in a misdemeanour conviction (being on their land without permission; being inside the building usually ups that to a felony).
You appear to agree with that sentiment - and you do say that you would "sleep soundly" if you were the trigger man.
You have admitted to, as I recall, "making dumb mistakes" when you were younger and picking up a felony conviction, which is a more significant offence than a misdemeanour in principle. That means you committed a more significant crime.
With that in mind, if you are okay with summary execution by shotgun for a misdemeanour, would you have been totally okay with your own summary execution by shotgun for your own felony?
If "yes", then at least that's consistent - if somewhat grim and very much lending itself to my earlier statement about normalising casual fatal violence (and then people wonder why the USA has a problem with casual fatal violence).
If not, then why not? Why is your felony not a capital offence (and bear in mind a lot of America thinks drug dealers - which you may not be, but from the outside a P/ITS conviction makes you look like one - are scum who should all be put to death) but the putative misdemeanour in the... "song" carries the death penalty?
