[MAIN SPOILERS] People are really exaggerating about Rhaegar.

Jaime - Pushes children to their death, fucks his sister, kills his cousin etc... Audience: He's a deeply complex character who can do horrible things but who ultimately has a good heart.

Tyrion - Kills the woman he loved, kills his father, drinks and know things. Audience: Best character ever

Stannis 'the Mannis' - Cuts the fingers of the man who saves him from starvation, burns people alive because of religion and boobs, burns his daughter alive. Audience: He's the MANNIS... Except for that last part though. Fuck him!

Daenerys - Has been burning people alive for several seasons, brought a group of ruthless killer and rapist to the 7K, is quick to order the execution of everyone who does not bend de knee etc... Audience: She's the legitimate ruler of the 7K and is just doing what she thinks is necessary to get in a position where she will be able to help people

Jon Snow - Is tired of fighting. It's all he's done since he left Winterfell! He hanged a boy, younger than Bran! Audience: He's right proper

Bronn - Mercenary with no allegiance who will not hesitate to kill whomever and switch sides in exchange of a castle. Audience: He's my beloved scoundrel.

Rhaegar Targaryen - Annulled his marriage with Elia Martell. Audience: OMG. What a freaking monster!
