[marvel] Why does J Johan Jameson hate Spider-Man so much?
gpt
There has been many reasons, because he thinks he's a bad influence, because he's a "clown". 

In Lee's books It's because he feels jealous of the power Spidey has and Jonah will never have.

Another big thing is that Jonah doesn't trust someone who hides behind a mask. He thinks someone behind a mask is a coward who won't take responsability for their actions, after all, the love of his life died because of someone with a mask.
