Of course not, but that's what not I'm saying. I'm just saying that leaving Maul and Boba dead would be such a waste of potential, its just plain silly. In such a sense they did need to be brought back, and I believe the positives outweigh the negatives (or rather 'negative' as the only bad thing is the implausible survival scenarios - which aren't that implausible.)
I mean, think of it like this:
Who raged when Malgus and Serevin were killed? I did, they could have given so much more. Who wants them back? I do!
Well Malgus has done a fair quite abit, reaching his own goals and all that. So I wouldn't say that he himself got wasted really. Though didn't the station blow up? I dunno if Malgus could survive getting tossed down a shaft, and then be able to get up and escape.
But anyway, focusing back on topic...ya Mace Windu is dead.
