Explanation of how this alters the character's personality:
A lot changes for Komaeda between his current canon point in Haven and his new canon point. There's a lot of disillusionment and desperation that arises because of what he discovers and goes through. After surviving a game of Russian Roulette (that he decides isn't challenging enough for his luck with one bullet, and so loads all but one chamber of the gun. This underscores how strongly he believes in his luck and sets the stage for what's to come). His reward for surviving the dead room is information about all of the students. Unfortunately this information is not good news for Komaeda. Though it doesn't explicitly tell the player the extent of what he finds out, his later communications and actions make it clear. He finds out at least a good part of the truth -- that he and his classmates are actually part of SHSL despair.
Since despair is the antithesis of everything Komaeda believes in, something in him breaks, to know that both he and the people that he has admired so fanatically are actually part of despair. He loses his eerie cheerfulness and optimism and basically sets out on a course to self destruct in order to save the one non-despair person who has infiltrated the group. He stages an elaborate scheme -- pretending to blow up the island and then staging his own suicide so that at least one of the other students will be "responsible" for it and thus the culprit. In his final communication (though it is corrupted by static and partially undecipherable) Komaeda explains that he hopes his sacrifice can earn him a place as SHSL hope. So despite his desperation and the meltdown that leads him to turn against himself and his classmates, he's still clinging stubbornly to hope and doing something to help hope flourish.
In the midst of his final scheme, Komaeda acts distant and dismissive, sometimes arrogant, instead of fawning over his SHSL classmates. It's not that his look on himself or his self esteem has change. He hasn't risen. They've fallen. But he still is clinging to the sliver of hope that he could someday be worthy of being called SHSL hope. He's willing to die for this chance and to take the people he now sees as abominations with him. He believes in his luck enough that it will work, that the outcome will be the right one. As such in his final communication, he addresses both outcomes in case only the "intruder" is executed.
Basically, with this change in canon, Komaeda has been hit in the face by a truth that he does not want to hear. He's still working out how to deal with it, but his first and most violent reaction is to remove himself and all his "despair" classmates from the equation -- though he shows at least some willingness to still believe in them at least a little, or he wouldn't have addressed them in his final communication.
Also he is "dead" more or less. In reality his consciousness is dead in the simulation that he'd been living in and his physical body is lying in the real world comatose. Initially he'll be very disoriented and confused about being alive once more.
Physically he'll be coming in with his real body, so he will have Junko's hand attached to his arm instead of his own.
