Malice implies intent to break the rules (or just the general conduct of the community). On one end, sometimes a user gets caught up in the heat of the argument and writes something they know they shouldn't. On the other end, sometimes a comment isn't particularly inflammatory at all but you can feel from the content that its author was in a place of of hurt, or anger. You can either label them as Malice and let the moderators sort out who are the real trouble makers and who just need some help, or you can reply to them in a helpful manner and possibly have a side conversation regarding their wellbeing.
I think it'd be a nice if there's a label to tell the moderators that "I think this user needs some talking to", for usage other than "I think this user needs a warning". More users are probably comfortable with clicking a label than putting themselves out there in a conversation about mental health, some may also not want to derail the discussion. Mental wellbeing and rule enforcement are 2 different skills with 2 different mindsets so having 2 different mod teams for each function probably also help.
This suggestion was partly inspired by, but not limited to, this comment by kfwyre. I feel that most social media's features (Tildes included with the way labels are currently) are designed to be content-centric and not much in the way of taking care of the wellbeing of their members, maybe we can improve.
