AP recently interviewed the actor Harold Perrineau
and described the incident as he "shockingly gunned down fellow passangers Ana and Libby to release the evil Ben and to retrieve his son from captivity"

I will reconsider my use of the word deliberate

but would still say its murder not nessarily premeditated

BUT Mike would do anything to save his son
same as Jin saying he would do anything to save Sun
{but Jin would NOT murder his LOSTie companions IMO}

I do think Mike is a dangerous narciss and ego centric to the max ..
guilt and shame MUST be fueling some of his hatred/rage

I also wonder why the writers chose a black actor to be the bad guy
{although Locke is looking increasingly problematic also.}

I do think Mike will be given another chance to redeem himself

I think Mike or Jin will die this wk
