Hmm.. I would think that it would be considered justifiable. Also, if it's like the original game, well, 'There is NO Eric' only a Victor here, so you didn't do anything wrong.. Really.Haha! But well, the game would end too, as MC would be arrested for manslaughter or something.
Other GOOD options:
1) 'Accidently' bump into EVIL scum on a HIGH observation tower and knock him off (where there are NO Cameras).
2) Arrange for a Piano to be dropped from a PLANE so it lands on the Lounge chair he is tanning on (Must be an Accident
3) Drop $1000 dollars into a Hippopotamus enclosure at the ZOO when only the Evil one is watching. Not sure if the Hippo should trample (or rape) him to death.
4) 'Fix' the Pools wiring so that He gets electrocuted. Such a SHOCKING death.
5)ALL of the above.
Just some PLEASANT thoughts.
