Hello , 
 
I love Marvel not as much as DC but love none the less. I do have one huge problem with them. it's the fact that for some reason there heroes must have a real life. 
it okay when it does not cause any real trouble like Spider-man have a girlfriend. My problem comes when the  hero does something un heroic or downright wrong beecause of that real life. 
eg. Reed Richards shuting down his own sons brain. regraudless of the reason no father would do that and no hero would ethier. in one move they take a hero who maybe was abit of a pompus jerk before and turn him to  
a terrible father and borderline villian. 
  
 
my only idea on why Marvel does this is to give there books on reality. for me it breaks it. The most real thing in comics as far as hero's real life goes is BAT-MAN. He as no real life, he understood that when he started being a hero.
 
in plan why does Marvel seem to want are there heroes to be Jerks?

DC does that on occasion. It depends. But yes, Marvel has a tendency to include more "realistic" stories (though, oddly, DC is generally more serious or dark)

So one hero turns into a jerk. There could be several reasons for this. Possibly a transition into another story arc. Tony Stark can be considered a jerk but it is part of his character, if they changed his personality im not quite sure anyone would like Iron Man anymore. Not everyone can walk the straight and narrow forever, somewhere along the line people slip up, even heroes.

"@PrinceIMC: See that scares me because that would mean  the Avengers (and Marvel writers) don't know what a hero is supposed to be.  I also think part of it has to do with the idea that Marvel heroes think they have to protect the whole world and not just there part of it. "

Nah it just means the Marvel heroes have a hard time thinking of themselves as paragons of virtue like Superman because they're just people. They live among the people not above them. At least that's how they see the DC universe. "
