He was just laughing with his pals at Kaneki's death.

we just know that his group was involved in some extent in the Rize's accident.

There are no other proofs that he was a mastermind, also because many events in the manga could have not prosibbly been known by him.

I believe that he just observed Kaneki for fun, but the only active things he did were to help in saving him from Aogiri and taliking about Yomo. He just had fun seeing him struggling to find the truth, but he didn't act to destroy his life. kaneki did all by myself.

This is what I think basing on what I've read. maybe in a sequel the author will fill che holes big as the moon to show hin as the mastermind of everything.
