It really feels like you’re stripping it of its teeth if somebody can control it, even if it takes far more training than not using it.

This kind of ties into something I wanted to post about TLJ in general. The Sith philosophy has a huge emphasis on the strength of the individual and that’s something I want Luke and Rey to teach their new students. It wouldn’t take anything away from the Dark Side as those who don’t control it will still “fall”. The allure of wanting to use the Dark Side exclusively will still be there but this will add an extra layer to the struggle future characters will face.

(As for the Force having its own will: There’s a lot of hints that it does. From Star Wars where Obi Wan says that the Force partially controls your actions

From what I know that only counts for stuff like being able to duel instinctively while contemplating something or conjuring power to unleash a powerful Force Ability and for instinctively raising up a Force Shield within a fraction of a second before a Force Push/Wave.

to Rogue One where Chirrut merely trusting of the Force lets him complete his objective)

I thought Chirrut wasn’t Force Sensitive…I recall reading that he used a bunch of other things to help him achieve his feats. If he isn’t Force Sensitive he was just trusting the Force to make things fall into place just like with the plot contrivances.
