Did Equius smile when he died because he got off on it or something? Or was it because Gamzee once said making Equius smile would be the biggest miracle and Equius wanted to make sure Gamzee got that miracle? I can't really remember. :V

He smiled because he was pleased to fill his role in the hemospectrum

aka, being oppressed by a higherblood

and that Gamzee was finally accepting his role as a highblood instead of just goofing off as usuall
