Unless you're a creature that lacks the ability to empathize then I don't see how you could not experience strong or harsh emotions for your characters. I have felt a variety of things through, or on behalf on my characters, even if they themselves didn't. In addition, I have also been through a lot when exposed to other characters even when I was totally uninvolved with the scene taking place or even so much as not even having ever roleplayed with the character. This is what makes RP exciting and interesting. If you couldn't feel anything from it then I don't understand why one would do it in the first place.
Characters: Andre Winter (Hy'ur) / K'nahli Yohko (Miqo'te)
