Or make a different achievement for each monster suicide since they are different difficulties

Like, have a demon self destruct with a barrel, or is there some other arcane method of self damage I'm unaware of?

Google "Doon barrel suicide" for details but essentially:
Monster hits barrel but doesn't destroy it
Monster hits barrel again with hitscan or melee attack
Barrel explodes, hits but doesn't kill monster
Monster then targets self and begins suicide attempt
Only melee monsters can successfully suicide because hitscan monsters can't hit themselves.

First suicide I ever saw was vanilla Doom v1.1 E1M8. Barons are good candidates for suicide because they have both a melee attack and enough hitpoints to easily survive the initial barrel explosion.

I guess you could have different achievements, one for monsters accidentally hitting a barrel and blowing themselves up and one for monsters that actually bite/claw themselves to death.

Another achievement: get a skull to kill a pain elemental. Player can weaken but skull does final blow.

In Doom v1.2 (and hence, GZDoom) it is no longer possible for melee monsters to target themselves as an enemy due to barrel shenanigans.

Causing same-species non-hitscanner infighting is way more satisfying anyway.

Wow, my Doom lore is way out of date.

Ok, just suicide by accidentally hitting a barrel then.

And how about a bad save game achievement? When you save right before you die, making the save game worthless.
