I dont know the answer but I have a few questions:
1. Are there grades of evil - greater evil and less evil, which, I think your scenarios are trying to create.
2. By whose standard do we base our decision? Our own conscience? General social cultural expectations? or by a poll like this?
I dont know the answer.
Majority voting doesn't make one action less evil - though the actions above aren't exactly evil. More selfish, as stated by one.
