My own thoughts: Jiren is a far better character than Moro. Moro is nothing but a goat magician who for some reason feeds on planets and strong guys. He has no ambition, no interest to train and no endgoal. He doesn't even say why he eats the creation of the gods, he just does.What has Goku lost? Every time he screws up and lets his family and friends get killed off and his planet destroyed, he has some magical way of fixing it, either with the Dragon Balls or Whis winding back time.
Barring Grandpa Gohan, Goku has never been forced to deal with the loss of anyone close to him outside of a brief period before he can fix everything with the Dragon Balls.
As for Vegeta, yeah he lost a lot more then Goku but he's also managed to carve a nice life for himself with a wife, two children, and a comfortable life on Earth. He's even found another group of Saiyans to help and kinda replace the ones that he lost in Universe 7.
Plus, like Goku, Vegeta never faces any long-term consequences for his actions since once again, the Dragon Balls magically fix everything.
You make fun of Jiren and act like him losing his parents and master is something he should just get over. Well, aside from the fact that he lost both at a young age, he also lost his village, and many of his fellow students to the same monster and the surviving students refused to help Jiren.
Oh, and he lives in a Universe where there aren't two sets of magic orbs that can fix everything.
Unlike Goku who has never been forced to deal with real loss, Jiren has been forced to deal with the memories of his failure and how he was too weak to protect those he cared about. Also unlike Goku who seems to have tons of friends who are loyal to him, Jiren had to deal with his brothers turning their back on him after their master's death and was unable to form bonds with people like Toppo as a result.
But you're right, Jiren's a whiny bitch because he can't get over the fact that he lost everything and had to live with that guilt that he was too weak to protect everyone he cared about, and deep down fears it someday happening again.
He should be more like Goku who has Dragon Balls that can revive people who get killed off, gods all the way up to Angels who are on speed dial, a button that calls Grand Zeno whenever he wants, magic orbs or outside help that bails him out when he makes a mess of things and the fact that outside of Grandpa Gohan, he has never had to deal with real loss or the real consequences of his failures since something always happens that allows him to fix everything that goes wrong.
"Majin Buu killed my family and friends, as well as the rest of Earth's population, and blew up the planet for good measure! Thank Kami that Namek has its own set of Dragon Balls!"
Yeah, Jiren should get over his problems and be more like Goku, huh?
Moro is a terrible character, probably the worst since buu.
But for some reason Jiren is said to be the bad character because it was poorly shown on the anime and not spoonfed to you guys.
