Alright, im at the point when Jacques offers to join, however he says hugo is evil and i should get rid of him.

Furthermore, when i talk to hugo (after dismissing him) he says the exact same thing about Jacques.

What do I do? which one is actually evil? does it make a difference?

well, what would be the point of the game if you knew everything. Just pick the one you like

If i agreed with that sentiment, I wouldn't be posting here.

I enjoy games more when i dont have to worry about being backstabbed by a character at an inopportune moment.

None of them have any dialogue later, so it's hard to say who is or is not evil. Maybe they just don't like eachother. Both are worthless in combat anyway, as are all followers.

It depends on what class you're playing. Having comapnions to draw aggro away from you is effective if you're a priest or thief, in which case they are far from "worthless".

SPOILER

is jaques a traitor too?

Where in the world did you find Jacques ive been looking all over haha

I stumbled upon Jacques myself today and he's inferior compared to Hugo (even though my Hugo was 2 levels under Jacques) in combat so I picked Hugo.

does the final of the game varies according to the choice between them?

I think south of Edgar von Hunth's estate.
