Well Lister's plan kind of faded out, didn't it? As I said, the cyber park mentioned would probably give the cat his choice of sexual partners. I would have thought that being around a genius such as Legion would please Rimmer. Not much of what you said could really be accomplished back on Red Dwarf.
It's an issue of imprisonment. Lister has always had an anti authority streak and thus co-uld not consent to be imprisoned with pretty strict rules (like the 'curfew', due to Legion needing every one to be in their cells when one of them sleeps). Plus, just because they haven't mentioned it for a while, Lister is still all about his plan and his farm on Fiji. To do that he needs to get back to Earth, to do that he needs a ship and Red Dwarf is the closest.
Kryten has to serve the surviving human (a point that crops up in White Hole- he doesn't really serve the crew, he serves Lister).
Rimmer, actually, hates being around geniuses, for the same reason he hates being around his brothers, they remind him of how much of a failure he really is. Plus, Legion was a genius when everyone around him was geniuses, now it's the dwarfers, he's no genius anymore, but still brighter than Rimmer (thus Rimmer would loathe his company- he only wanted Legion to go with them because it would increase his chances of survival and he's used to being hated by everyone around him).
Which leaves the Cat. You every tried trapping a cat in one place? They don't like it. Basically, staying doesn't actually fit any of the characters except Kryten. Also- note that Legion hates them as well and is quite relieved when they escape.
for stupid decisions, anything Peter Petrelli does in Heroes (Like when he goes to save Claire from Sylar in season 1 "I don't have time to wait for the man who can go back in time, or at worst, pause it!"), anytime a character in Heroes lets Peter make a decision.
