You're saying something that doesnt even is related to his love at all, nothing happened to his love after he died, he still loves her on the same way, you're talking about other stuff like his objective, his love wasnt the reason why he became "evil" but the fact he lose everything and how he lost faith on the world.
He's not wanting to change the world because of her, he doesnt want her for himself this is being selfish.
He's selfish not because of his love for her which he clings because those are his fondest memories, the same way Sasuke clings to Itachi, and Naruto/Sakura clings to team 7 do they are selfish because of that?
That was to shown how Kakashi knew about it, althought we have no clues about it but we have Naruto thinking of winning to chuunin exam with Sakura being one of his motivation, and his thinking about "maybe when i came back she will love him" and how he wanted to act cool in front of her and stuff.
Those examples are fail to appoint that his love is n obssession, because Naruto did similar things on the manga, like shapshifiting into Sasuke and almost kissed Sakura.
Obito's is selfish because he's close minded and is entitled to his opinion, and the difference between Naruto and Obito is that Naruto managed to have more bonds, and Obito lose everything because of what Kakashi pointed out, he lose everything because he hasnt managed to make other bonds or find a substitute for Rin and Kakashi, he lose his team, and instead of finding another one, he used his loss as a motivation(to not want those things to happen again) to change the world, ofc he's doing on a selfish way but it doesnt make his love selfish.
It did happen , he awoke the Mangekyo which practically makes you fall in eternal darkness thanks to the special sprouts which are released from the brain or w/e they are called .The fact that she died triggered that pattern and made him go unstable . He had no one except Madara to ''help'' him .
His goal is selfish , he'd rather trap the whole world in a make believe universe, punish innocent people in the process , maybe he will create a fake Rin to be beside him? Rather accepting the fact that ''you can't save them all'' and live in reality . Its true that he wants to convert the world , but in the process rob the people of their free will and that's what makes it unacceptable . Yes, he had no bonds but he did have a family and Kakashi , he didn't try hard unlike Naruto.
Kind of both. If he only wanted to have Rin he could have brought her back to life with the Rinnengan or maybe used the Genjutsu upon himself only. He believes he is some kind of messiah trying to free the world from the curse of hatred.
Itachi warned Naruto that he isn't the only one that can change the world that's why he reminded him of his friends and not to become Madara/Obito 2.0.
