Turn on or off your emotion. I would like to have that ability since I can see it being useful in future situations.

You do already realize that some people can already do that right.

Ted Bundy could do it, Richard Ramirez could also do it an nearly every other serial killer known to man.

I have emotions. That is wrong. I wish to erase them.

I already can.

I guess. Although technically you don't have to turn off your emotions, just become a stone cold [censored].

No. Everything I do is because of emotion.

If I had none, I'd do nothing because I feel nothing and therefore can't do something other than nothing.

I couldn't laugh, joke, get mad, be happy, feel sad, I couldn't think for myself about various subjects...I'll keep my emotions, in this little glass tub, thank you very much.

Teach me your secrets oh wise one!

The drawback I see in that is... if you could turn off your emotions at all will, wouldn't you still have to deal with the emotional fallout of those actions once you turned them back on? For an example, if I turned off my emotions so that I wouldn't feel guilty about doing something that I'd normally be unable to do - I'd still have to deal with the guilt once I could feel something again. And then there'd be the slippery slope of I wouldn't want them back "on" because I was having trouble dealing with that guilt from whatever it was I did, yet while I was unfeeling and uncaring I'd be even more likely to do other things that I'd later regret, which would in turn make it even harder for me to deal with that regret, which would lead to me wanting to remain in that "emotionless" state forever anyway.

Hmm... kind of sounds like a lost Philip K. dike story, come to think of it...

Emotions are what make us human, why would you want to turn them off?

People forget that things like compassion and empathy are emotionally charged, if not emotions themselves. We would never feel anything about anything, and be living in a cold world and not even know it. Lots of things in life are charged by emotion, we just forget that because of how used we are to it.
