Dying Declaration of Love: The character dies happy in the knowledge that they were finally able to spit it out.
Die Laughing: Usually the most benign form of this trope is the one at play: the character laughs because they die genuinely happy.An Immoral Nihilist might just die happy in the knowledge of how much destruction and death they caused before dying. A jaded Blood Knight might be happy about being defeated in fair combat. A chronically depressed, Death Seeker or sick person might see death as a release and welcome it with open arms. A just Hero might do a Heroic Sacrifice for their friends or to save the world. Both The Unfettered and The Fettered might be willing to die as martyrs for their beliefs. A character who's in love might sacrifice themselves to save their love's life, or die so that they may go on living happily. Of course, what the dying character's perfect death is like will vary wildly depending on said character's personality and outlook in life. They might not even have accomplished anything significant, but just lived a good life and believe that death is only the natural last step. They know that whoever they leave behind will be okay, or might even benefit from their death. The character dies satisfied, with no unfinished business. They have no regrets, they accomplished their goals, and while people may mourn their death, they know that it was not in vain. A character dies, but their death is exactly the way they wanted it to be.
