He's a monster.

The crying before Sarutobi thing was sarcasm. And even if you take away the Root stuff, he was still doing heinous acts all the way up until he was absorbed by Sasuke. He even threw a hint during the war of his plans to continue his "research" and mentioned that the reason he decided to fight alongside the Allied Forces was because he didn't want do so in a world under Obito's control. He just simply gave up trying to take over Sasuke.

He did express some remorse for Jiraiya's death, but that was about it.
