That's weak wanna hear a real torture method

Tie the person that wronged you up then

Put nails through both arms and feet preferably rusty not necessary though

Then i have like 3 methods but i dont really think mental torture only is enough so 2

1. Tie his tead back and remember that drops of water thingy, now scrape skin off the top of his foreheads then put lemon juice to dripple down drop by drop in lets say 2-5min intervals so it gives them a little time to mentaly and physically heal. After a bit of time (all this while they're tied up to those hospital thingies that keep you alive so they dont die on you) after the nails have rusted and the limbs have been poisoned you cut them and put nails in the new stubs and repeat

Now the other one

1. Tie them up and cut their hands put a food that smells really good in front of then but make the inside full of spiders (or any insect really) also now that i think about it make splits in their skins and pour spider eggs in said splits. They'll eventually eat the food and be disgusted by it but have no choice but to continue after being bit a bit (no pun intended) (make the spiders not very poisonous for them to die of it or get much harm from them but enough to make them feel pain like hell) after a while of this cycle some of the spider eggs in the splits that you sowed back up will hatch and start eating them from inside until they die

His method is not that good since they could break it or get in a position on which they could not get harmed at all by rolling around in a corner or smth like that
