I'd go with the mind reading, primarily because I really don't want to kill everyone. I'd move out to the country if my mind reading was uncontrollable (e.g. I hear the thoughts of everyone within an area all the time and can't focus it down to 1 person). Then I'd start a business of telling people their heart's desires (reading their mind) or something. I'd be a personal development guru, or something. People would have to drive out to my home, and I'd need to hire security though.
Given the criteria in the OP, I'd take neither. If I HAD to take one, I'd do the above.
