I consider this more of a fun, cursury run. I need more subjects for anything serious, 100 would be ideal. I am also using a ton of hidden aspects. Many times it points to a minor talent (in action based ruthlessness).
I think two things prevent the base use of the Mars-Pluto enegy: conscience and success. You may have it, but due to the empathetic/high conscience part of you, the energy may never come out as anything more than spectacular fights. The second criteria is success: those with a high caliber for success (regardless of conscience) have a lot more to lose. They may channel the energy to other deviant ways, but it does not include murder.
