The Jerkass Monster

''I'm gonna destroy everything... for the lulz!''

The Jerkass Monster is the Monster (figurative or literal) that goes around and causes general destruction for no reason (other than...). It gains nothing out of its destructive rampage, and the people affected by it are completely devastated. It should really be ashamed of itself for what it's done. If it actually is ashamed of itself, it would either try to fix things or just run away and never be seen again. Most of the time, it just doesn't care and needs to be stopped by someone to end the chaos it's caused.
