Yes, emotion does influence my decisions and I don't think it is something to be handled.
Emotion is a big factor in our lives, so there's nothing wrong with being emotional while making a decision. People think they're making a rational decision but essentially, there's always the emotion part in their conclusion. Even judges in courtrooms make their verdict being emotional while trying to do justice.
I'm not saying that it's good to make a decision entirely by one's emotion, but it's good to have some parts of it other than the rational factors.
