Love means different thigns to different characters. Some of my characters have had it, others not. In no particualr order:
Vorhi's love is entirely past-tense at this point. Part of that is the reason he plays the bitter drunk act so often, but really, he lost the last person he loved to violence, and he doesn't have a knack at living peacefully, so he avoid the idea of love itself pretty handily.
Olidiv Kenu never really loved people, he just loved life. Dude's a hedonist and flirt, he doesn't love, because love's a commitment, and why would a millionaire playboy mercenary actor commit to one lover? It wouldn't sell well in the tabloids, that's for sure.
Olom was part of a entire species of cold, intentionally emotionless geniuses, and that was before he became a Sith. He views love as the most dangerous and temperamental of passions--powerful, but nearly impossible to control. And he dislikes anything that isn't controllable.
Mr. Ash/Amaranth was a love story, but not a romantic one. His love was familial, and it was to the Black Suns. That's why he lived for them, and that's why he "died" for them. Amaranth is not Ash, but she's not
not Ash, either. Hard to say where her true feelings are. But Ash was a true, sincere, and genuinely loving droid--despite being designed as a professional hitman originally.
Mayhem was never loving, although she did show a fraternal respect for other warriors, droid or organic. That was her way.
Jeffar was twisted, I don't know what love would have even meant to his addled mind. Could mean slavish devotion, could mean abducting and a stalker thing, maybe a little of both. Hooray for playing mentally unstable messes!
Sugar is just too much demon for one person to handle, I think.
50H31....I don't know yet. Still need to explore his inner workings a bit better. I think right now, he'd view love as yet another curious ideal of the organics.
