If you could have a geass...

[elly3981.livejournal.com]

Would you want one? What kind would you like and why? Would you be able to handle the side-effects? Those who paid attention to the anime knows that having a power such as the geass comes with a price. For me, the thought of having people obey my every whim, read other people's minds may seem appealing at first, but if I was really offered such a power, I'm not sure if I would want it because I might be tempted to abuse it or even worse, be driven insane by it. Any opinions?
