Because quirkless Deku had heroic characteristics. Bakugo who had a powerful quirk, felt inferior to a quirkless at an early age, and started hating him for "not knowing his place as a quirkless". Don't quote me though, I'm paraphrasing. That's basically the start of the hate. And after Deku "develops" a quirk, it just adds fuel to the fire.
Can someone tell me why bakugo hates/dislikes deku please
