Not necessarily, atleast not any more than LS or DS "choices" move your alignment one way or the other.
For instance, if you use Force Choke one time, then your alignment shifts ever so slightly. That way you don't suddenly become a DS by using it one time, but you do, eventually fall to the DS after repeated use.

Sounds like a good idea. Using darkside force powers too often and it starts to corrupt you. It makes sense, look at Lord of the Rings and the Ring of power. It slowly corrupts those who touch it after a while.
