OMG YESSS THANK YOU SOOOO MUCH!!!
I remember it started off with this guy getting transported with his class to another world and the god gave each and every one of them powers except him or something like that and if I remember correctly in his next life to make up for that he was given a power of like healing/ regeneration and the people experimented on him and then in his most recent life he thought his bad luck was over since he had a family and a peaceful childhood but then people killed his mom and he wanted revenge
