It’s horrible to say it that way. “He passed,” is a phrase I cannot use, although I recognize that others take it seriously. “He died” sounds active, like he went and did it. I say it horribly because that’s the way I feel about it.
BONUS POST: Thanks to Larry Lade and his April pledge at the Doctor Xaos Patreon! Lockdown first: I’m restricting this conversation to the first six-issue series Marshal Law (collected as Fear and Loathing), because both further development of the line and fandom have defiled it, frag them. I bought it issue by issue in 1987-1988, delighted and stunned.
