Tasuku joined DIsaster because he thought that the Buddy Police were becoming corrupt, which was due to Nobari and Kyoya deeds.

Due to this, he felt that the only way for him to acheive his goal of fixing the wrongs of the world, was by joining Disaster, and up till his release, he felt that he was doing the right thing. Kyoya, purposely, fed him the info that DDW was invading, so he felt that it was his job, with his Disaster Force, to fight against the invaders.

He never doubted in his decision, as he felt it was the only way. He never intended to outright destroy or follow disaster, however, he just wanted to help, and felt the only way to do that effectively, was through Disaster. It was...a front. His feelings of being the Purgatory Knight, it just 'appeared' to be a change of heart as he was still being Tasuku, just darker.

(I know I, in effect, said the same thing three times, but at least it's less likely for you to understand.)
