Injecting someone with a lethal dose of a drug no less kills them than putting a bullet through their head. My suggestion would kill a person almost instantly, the person wouldn't feel a thing, the only downside is the gooey mess you have to hose down afterwards

The executioner might object to seeing the results, and paying someone to clean it up would be extremely expensive (you WILL clean it up - it's a body and a biohazard). I guess it might also be worth mentioning Nazi death squads. The Third Reich didn't move up to extermination camps only for efficiency but also genuine concern for their own guys who had to personally shoot defenseless civilians at close range. Death squad troopers had to be recycled frequently or burn out and many were badly traumatized. Industrialized death made it less personal and easier to kill.
So in short different "humane" execution methods aren't just for the poor guy getting executed, it's to make those who condemn and execute him feel better about it.
