Mature rps do this alot, aslong as people are okay with mature themes and it goes with the story (it fits obviously). It can provoke a good emotional response. It's not something to avoid by any means, mature rps usually hit for realism or take ideals from it. The one's I've been in, anyway.

When I do it I woulden't have my character do what they woulden't do, it can be fun, it can make people cry.

It's a good tool for emotion and impact of actions.
