Ignoring the whole transfer saga I wouldnt want him back for the simple reason he is not a good player now. When a player who is only good for scoring goals cant score goals anymore he has no room in the squad.
That's a bit closed-minded. Chelsea and Benitez's Liverpool play(ed) totally different brands of football, and Torres is not the all-rounder many people think he was. Horses for courses. Were he still at Liverpool Kenny would have him scoring at his career average (or better) without any problems whatsoever. After all, he scored more under the King in 5 league games than he has thus far for Chelsea in half a season, and he managed to be completely untroubled by injury the entire time. Class is permanent; he's just at the wrong club. Not saying I'd want him back, of course - he'd probably get into a fight with Carra first day back for betraying us.
