1. Jack has little qualms killing most people.

2. Kasumi, she can practically turn invisible.

3. Wrex is pratically a newborn while Samara has hundreds of years under her belt.

4. Udina, especially since he becomes indoctrinated in ME3 (according to the leaked story files at least).

5. Liara I guess.

6. This one is somewhat difficult, but I would assume Legion because he is a machine.

7. LotSB, Arrival wasn't all that much in my opinion.
