Mass murder is not always an act of desperation or weakness. Sometimes it is a simple act of exterminating groups whom you believe are OBJECTIVELY unfit to go on living. It could be for your benefit, society's benefit, the planet's benefit... For whatever reason, you can just believe that certain people/groups should cease to exist.
If I exterminate all the bed bugs in my mattress, am I being weak? Am I "unable to face my problems?" Am I throwing a tantrum? No. I am ending the infestation of creatures whose existence itself IS THE problem according to OBJECTIVE FACT. So if you think mass murder of humans is a sign of weakness, desperation, or in any way can be compared to a "child breaking their toys", then next time you find rats in your kitchen, do the ADULT thing & LEAVE THEM THERE. Let them eat & sh!t in all your food. Let the bed bugs multiple, keep you up every night & leave bites all over your body. Let the hordes of cockroaches run free. Be responsible: Live amongst waste. See how that works for you.
