Can a sadist still be a good Master?

I was reading the update on Tyler and the pull that Alpha Adam still has over him. In some ways it is similar to my situation since my Master is also a sadist who enjoys inflicting pain. Are these types of Alphas good for faggots or should they be avoided? When does it become abuse? I think I am afraid that I am already too sucked in. Even if I do get out of a potentially abusive relationship I think it is likely I will just find / attract other destroyer alphas so I would be right back in the same of even worse situation. The whole thing feels unhealthy.
