HOW TF DID THEY GET TO THAT POINT WERE THE MANGA BEGAN?? ITS LIKE PEELING A ROTTEN ONION SO MANY ROTTEN LAYERS
so here's a theory. Law scared of losing Jesse wants to control him gets his wish after Jesse descends into madness due to his parents death and other tragedies. to erase said tragedies Jesse wipes his mind. Law doesn't mind he still controls him. only now Jesse doesn't trust and know him anymore. also like it was said when you loose your memory you will look for your lost memories hence remembering what you tried to forget in the first place. hence several memory wipes later Jesse's mind is confused er go memories confused he thinks law is going to hurt him or even hurt him. Law gets tired of this and maybe tries to kill him or actually hurt him or may be considers hurting him but instead jesse offers to erase his memory completely this time. Or instead of hurting him Law forcefully wipes Jesse;s memory or even edits his memories to get control of his company etc
