Weyland wanted to play God, and did, via creating David. So, David feels he needs to do the same given the time and resources. It's a simple jump to give a synthetic those two things. He isn't necessarily being "evil"...only dead set on a task at hand, the way all synthetics are supposed to be.
Another warning from Ridley concerning the worry about what is to come via Alien/A:C and Bladerunner.
