Why The Hulk Refuses to Appear in Avengers: Infinity Wars

For those reading this blog in the future, we are in the interim between the third Avengers movie and the fourth.  There are many unanswered questions about what happened and what will happen.  This post is of course a spoiler.

There are many theories about why Hulk does not want to appear and fight in Avengers: Infinity Wars, but I believe I have a special insight.  People want him around to fight their battles, but then they want him to go away and turn into Bruce Banner.  In other words, they dont really love him, they love the other guy.  They just use him now and then.

Well, this pisses him off.  Wouldnt it piss you off?  I am guessing the Hulk is saying No, love me and have me, or dont love me and not have me.  Your choice.

Thats my theory.
