All daemon wanted was to be accepted. Nobody accepted him as he is. He has bad temper, he craves war but the thing he needs most is acceptance. Viserys always loved him. Daemon knew he is worthy of the throne. Daemon wanted it so badly but the love of his big brother stopped him everytime. Daemon run away, burned things, fought war just to stay away from his brother. If daemon wanted, he could've conspired against Viserys and take the throne but he didn't. Viserys is the only person that accepted daemon as he was, loved him. Everytime they fought, daemon came back and viserys welcomed him. Other than Viserys, Rhaenyra accepted Daemon. Daemon always had eyes for Rhaenyra even when he was married. I can relate to this because I have a big brother. No matter how angry I get, how bad we fight. Everytime I come back, he welcomes me with a smile. As if he knew, I'd always come back.
