Snake in the grass 

Someone who pretends to be something other than what they are, while hiding a nefarious agenda.

Note (1.) A snake in the grass doesn't have to be sadistic, but they have to be self-serving enough, they don't care who they hurt in the process of achieving what they want.

Note (2.) The term "snake in the grass" has been around a long time. Long before people had lawnmowers, or constantly trimmed their lawns like a military buzz cut. So the grass metaphor used to be more obvious. When the average person's lawn used to grow past their ankles..snakes were rarely visible.

If you want to describe a cold blooded human with hidden intentions, "snake in the grass" isn't a bad choice.
