There isn't a murderhobo alive who would talk shit about the healer, let alone kick him out of the party.
It's like the manga or light novels where the party is like "All you can do is heal, you're useless!" Bonus stupid points when they do it right after said healer saved their lives. I think I remember one manga in which it began with basically what should have been a total party wipe, but the healer managed to use powerful healing and support magic to get everyone back into the fight even as they got their asses kicked. Right after the fight, still standing over the enemy's corpses, they kick him out for being "useless" because, I shit you not, "all you can do is heal". One of them had, in that same fight, been killed and the MC healed her wounds and resuscitated her. IIRC, she also supported kicking him out.
