nah, just Michelle.
Palmer's death made sense in the grand scheme of things. Without it, Season 5's plot would not have existed (Jack wouldn't have got back into the game). His death had weight, meaning and considering his story up to that point was totally played out, it was the right time. It was totally right. His body's send off with the rifles whilst his musical theme was played full forte at the same time Logan was being escorted into custody was one of the greatest moments ever in the series and a true fulfillment of everything that Palmer stood for.
Michelle's death only really served as a plot point to get Tony annoyed and then killed. Which, considering Tony didn't die, meant her death was essentially a "lol, cya" death more than anything else. It meant nothing - Jack didn't even seem to give a shit. Sure, they tried to add similar weight as Palmer's death to hers with the events of Season 7 but that made no fucking sense in the end and felt hollow.
As for the others who died in S5 - Edgar was a pain in the ass. Thank fuck he died, and thank god it was painful. Henderson? Well, he needed to. Anyone else? Nope. Aaron survived, thankfully.
yep, it was just Michelle.
