About cults?

So I was watching this tv show about serial murderers and it involved some leaders of a cult and that got me thinking. Could I start my own cult?
I think to start a cult would not be that difficult, but to maintain and especially maintain a healthy cult would be a daunting task.
As we have a lot of examples of cults gone bad it seems it's very difficult to not fall into that pattern of abuse by the leaders. But what if one could overcome that nasty part associated with cults and actually shows good leadership? I think it could be done in some way but then again it would probably not be labeled a cult but a movement.
Maybe I will start my own movement then.
