They all are fully into it, except force users that distance themselves from it, or are cut off, like Qel-Droma or what's his name.

The difference is this.
Light side takes a hands off approach. It maintains, it acts at a distance. Some say it's the Force itself as per Lucas, but SW, being occult, vastly outgrew its supposed makers.
The Jedi follow its will, use it only when necessary, moderate or extinguish passion.
The Dark Side, being part corruption of the Force, part its natural property, has its own will too. Its will is to enslave and destroy. The Sith strive to control it, It strives to control them.
It is eager, it hungers. It pushes passion to the max. As it is more proactive directly, so are the results.
