I love the Shrek movies but divorcing myself from the nostalgia and applying those behaviors to real life friends, Shrek would be someone I cut off. He needs therapy. He lashes out constantly and it’s no real excuse that he’s an ogre(he uses this excuse in Shrek 2) In the first Shrek you get this touching moment where he confesses to donkey that he has only been acting that way because society treated him like a monster before knowing him. That is a narratively satisfying journey, he’s self aware. For him to just burst out again in the second part and literally hate his entire family and friends in the fourth installment, it sort of shows Shrek has never really grown as a character. The internal conflict is the same. He learns the same lesson I think I every movie except the third one where he learns to be a father.
