I'd say no.

When he is first confronted by Jerome near the end of his maze, he notes how Jerome killed their mother, and seems genuanly upset by this, his voice sounds shaky. Soon after that he is held at gunpoint and looks absolutely terrified.

When he is first sprayed with the laughing gas, Jeremiah is seen desperately trying to fight it, he DOESN'T want to turn into a monster like Jerome and keep his legacy alive. He wants to get on with his life without having to live in fear. And as soon as the laughing gas takes over, Jeremiah's good side is essentially gone, and the Joker takes over, laughing maniacally.

When Jeremiah says that the gas didn't do anything to him, you have to remember that after transforming into the Joker, Jeremiah become incredibly arrogant and overconfident. He even stated his plans to rebuild Gotham in HIS image, whereas before all he wanted to do as an engineer was build and keep Jerome away from him. He became deluded after the gas transformed him.

During the fith season, the gas has began to completely warp his mind and made him even more deranged and obsessed, this is why he threatens Ecco before Selina stabs him and never did it in the fourth season.

I'd say that this version of the Joker is a deeply tortured soul, regardless of whether his stories about Jerome are true or not, no one knows. What is known is that he was, and always wanted to be a good man.

So I'd say no, he is not pure evil and has redeeming qualities that make him much more sympathetic than his psychopathic brother.
