While others are focused on killing Liara or other team mates ... In my game Shepard with his crew, Liara included, will be focused on killing these ....

So go forth and kill your own team you wild and crazy Shepards! 
Killing the Reapers is business. Killing the squaddies is pleasure, and can be easily done in Shepard's spare time, or during a coffee break.
And after putting up with them for so long, Shepard deserved the right to kill whoever he wishes, in the most gruesome way possible, and save whoever he wishes from certain doom, in the most glorious way imaginable. Interactivity is what I love about playing a game.
