Morality being fundamentally subjective, I don't see amoral as necessarily a bad thing. You don't need morals to have a positive impact on society.

Lazy is not handy, but then again I'm not convinced that people can't be motivated out of this. Wars and other really unfriendly things cost a large amount of effort from many people. Laziness is seeing problems and doing absolutely nothing about them, not doing the wrong things. That's just being misguided.
