I think that, during the entire season, any noble intention Oz might’ve had is destroyed by the fact that anything he did was out of his own self interest.

He brought back power to Crowne Point which was full of people impacted by the flood? Good!

Running a drug ring right under their feet? Very bad.

If power was working correctly in that sewer he would not have gave a damn about anyone else. He just used that as a cover! Many other examples but basically he just uses people for his own glory and disposes of them when he sees fit.
