Even if Jellal had no choice but to obey, he can still blame himself for being too weak to resist.

After all Erza might have gone through the same thing, maybe even worse (like getting her eye plucked out), but she had enough strength of will to resist it untill she was rescued. And while we didn't really get a timeframe on either torture, I got the feeling Erza was in that room longer than Jellal.

As for the Rogue matter, he definately is innocent, since he didn't commit the crimes yet. That being said it might still be a good idea to kill him to prevent this catastrophe, IF it really is a reliable solution, but they can't be sure that Rogue's death in the present cascades through to f-Rogue.

Actually with f-Lucy's memories staying the same even after she changed the timeline (she prevented her present self from being re-captured, but still remembered being captured herself) and with f-Lucy and f-Rogue having memories of different futures everything we know so far points toward killing Rogue having no effect of f-Rogue, except perhaps pissing him off.
