No Good Deed : What was Colin's goal?

What was Colin's goal?

With terri and the kids? Was it to kill them to take revenge so Jeffrey would have to live with it? And couldn't work out his plan. Considering he was wreck less I don't think he knew himself. Obviously with terri killing Colin it made me think what was he going to do in the end?

Re: What was Colin's goal?

As a recently released convict (of murder?) coupled with a psychotic disposition & whose life amounted to one unmitigated pile of turd, he sets out to destroy his girlfriend's & her married lover's family. A sub-prime plot featuring a couple of prime actors ... what were they thinking in signing on?
