>You can't use both light and dark side. You can't be both good and evil
Luke Skywalker uses the dark side for "good" (which again is just a point of view)
>you must sacrifice everything
Palpatine loved power and did not have to sacrifice that to reach his full potential.
>you'd have to murder your whole family
No you don't. Count Duku never did anything "evil". Neither did Luke (who didn't use force lightning but certainly could have if he wanted to enough. Force choke is definitely dark side tho and he does that without any hesitation).
