necromancer that offers terminally ill/old or desperate people a significant stipend to their family, in return for being painlessly killed and brought back as an undead servant.
and because it's good free PR, the necromantic thralls get to visit their family (or just pen letters if on campaign) during downtime.
They're not empathetic or anything, they just don't have any desire to actively harm normal people and recognize that being at least mostly tolerated makes everything easier.
