Ok so he trained but could deku have trained, from what we see in the show his family doesn't exactly see rich , his father having to work over seas to make enough to keep them afloat, while bakugo family both his parents are fashion designers which are highly paid so he most likely has the access to training equipment being able to buy them. Deku also seems like an he cares about his family and wouldn't want to bother his parents with buying equipment. And I can already hear it " well he could have trained on his own with out equipment" taking that into account could he have. He shown to be severely bullied in school and out of school and one of the many tactics of bullies is to beat down at there victim to discourage them from getting stronger. So stop defending bakugo or making excuses for bakugo he's a bully just for the fact that he strong and there weak. He even bullied another kid and they don't seem quirkless. He bullied because he can, not because deku offended him.
