It was a lie of ommision. That's something he should have fessed up too since it affected the team so much. It must have hurt to know one of your teammates was partly responsible for one of the largest slaughters they had seen and lived through till that point.
He did offer the truth about the Massacre to Rogue before his trial, so slapping him with the "lie of omission" part isn't fully true. But before that I don't blame him for not telling them all about his darkest secret since he barely knew them and was still used to people stabbing him in the back: telling them about the Massacre would've been an idiotic thing to do.
Aside from a few like maybe Storm, Rogue, Jean, Jubilee, Wolverine, and Beast, I dont really care the X-men really cared much for him. They were more like aquantices than actual friends. Im sure most werent losing much sleep at the thought that he was gone.
1: None of those people came looking for him. Even Rogue's retconned attempts to find him don't fit in with her busy schedule of picnics, finding a doctor to cure her powers, and fighting for team leadership.
2: The X-men are supposed to be a family. And that means you look out for them even if you don't particularly like them. Basically, they all acted like hypocrites.
As far as leaving him, they were all trying to save themselves. The only person at that point with any means of saving him was Rogue. She had the flight, speed and strength to do so. The rest were just trying to get close to Betsy as she could hold her shadow-port for long.
They knew something was up. They just apparently didn't care enough to question her about it or go back for him after they returned to the mansion. Even Rogue's returns are BS: she flies at supersonic speeds and he was crawling on her hands and knees: she would have found him before he had gone half a mile.
As far as Rogue's actions, well she had just absorbed Gambit's dark persona and it was suggested that that was partly why she did what she did. I know, not the answer you wanted to hear
And that was BS, as gambit later said.
1: Suicidal people do not struggle through miles of freezing hell and fuse with energy people and make deals with mysterious benefactors to stay alive.
2: if Rogue can't keep her self-control after absorbing someone, she has no damn business being on a team and going into combat situations.
Why shouldnt they? Life goes on. They had all suffered over those past few months, with Onslaught, losing Xavier, being lost in space, OZT, having their home cleaned out, nearly losing Scott. It was the first time in a long time where they actually had peace and nothing was going on, so they took the time out to relax.
Yet they couldn't find time to go back and save someone they had all condemned to a slow and painful death? Whatever crimes he had committed, that was just wrong on their part. I'd go so far as to call it evil. They aren't judges, juries, or executioners.
If he kills anyone in #200, it'll be comeuppance IMO.
As far as Storm, well Rogue is her friend too and has been much longer than Gambit. She wasnt going to turn away from her
Storm thinks of gambit as a brother. They're much closer than Storm and Rogue, and Gambit's situation was far more perilous. Storm should have tried to *save his life* before worrying about rogue's bad dreams (seriously. Look at what I just typed: Storm was more worried about Rogue's *bad dream* than Gambit's *life*. I dare you to say that isn't screwed up.)
Rogue was the only one on the X-men team that was there when Gambit was left. The rest had moved on. I dont think Colossus, Kitty, Nightcrawler, Storm or Marrow had anything to be apologetic about as they had nothing to do with that nor were they around.
They would have found out afterwards and the fact that they knew what happened and didn't bother to go back makes them guilty. in a court of law, they'd end up with jail time because of that.
