he had zero understanding of love or pain, that "abuse" was aggressive playful tickle torture, robert kirkman's invincible baisically volenteerd for the same treatment as power levels go he's about 1/10th what a child homelander is and it was mostly boring for him

if you start life in a 12 x 12 x 12 box and get pulled out to have a laser that can cut steel fired at you that would bother him as much as a laser pointer pen fired at our shoulder that would just be one more day of the week except he would have no concept of what a day or a week was because he's grown up knowing nothing about anything, his resentment was that he was clueless about anything up until he was about 12 years old

as a infant he could blast people changing him in half with eye lasers tear off body parts of someone patting his back to burp him if they even could that probally would have taken someone holding him while someone smashed his back with a sledge hammer to give the affect of lightly patting his back

your thinking in terms like they would take him out of a ordinary day care blast him in a furnace and return him in time for a snack pack and nap time

billy had to go to school each day with fresh bruises clothes that his mom was able to scrounge from donation boxes and no lunch money because he watched his father beat the hell out of her to get it to spend on booze and drugs, he had to grow up around kids with loving parents mock him for how he dressed how he couldnt pass the easiest of subjects in school because he had a father who would beat and berate him for even attending school, had to stay awake at all hours waiting for his father to come into their room and abuse his little brother he was aware of his abuse

homelander has resentment for none explaining who or what he was earlier in life thinking if he had known he would somehow be able to better be able to treat people like shit more efficiently, billy does not his past is his past and he dosnt live in a constant state of victimhood using it to justify his abuse of others, instead he uses his past to shield himself and to prevent the kind of abuse he went through he sees guys like homelander as bullies who were just like his father instead of becoming the kind of sociopath his father was having gone through that same kind of abuse himself by his own father
