"loser, bastard, coward." being quirkless was looked upon as an outcast, the 'bad part' of society. even though, the world was once quirkless as well. when you get a quirk, they get categorized. of course, you were unable to fit into any of those quirk categories, for you were quirkless. you were deemed as "hopeless" in the society. which gave you the desire to prove them wrong. it wouldn't matter which path you would have to take to prove them wrong.
