Your rage to the extent of want to kill and korek out their heart I cant understand becuz however much I butthurt, killing dont come to mind at all But from the way you describe, it seems these 2 ppl has planted much agony in you thus maybe they deserve it who knows. Hope you good luck in achieving it and may u rest in peace thereafter. Do post video or some drillz or proof of you done so here too.

Killing or vengeance is not right but as seen on tv, it is sometimes justifiable but as said again it is not right.

I have a suggestion maybe you can do minor things such as pancitkan tayar or bakar kasut or baling cat at their kereta instead to try quell the hate. Maybe it works and even u get caught u will still feel puas and duduk jail few months only
