Alright, let's get a few things straightened out.
There are no aggressive snakes. There are some defensive ones, though.
Given that, ANY SNAKE can be raised to become a calm, trusting and tractable adult. I know because I have done it with every giant species, except for scrubs. But a snake is a snake is a snake. Teach it early on to trust you, and you will never have a problem as long as you are not stupid. ie smelling like food, bothering it during a molt, etc.
