One thing that takes people to kill

And was a movie that I watched, you know something that drives someone to kill is the fear of be discovered that cheat, that wasn't the friend of person, like that you came someone friend and the intention was betray, to be discovered as a traitor as the intention was to harm to betray to watch, that the friendship was all feigned, so is the shame that one person that is betrayed could make to the betrayer with the eyes that words that harm, so the person kills to don't pass for that, and once the person dead, all the plot of the treason is hide, because the person really was helping, the bad-good of that person is that if you are really good they thing that hey doesn't accquieve to destroy you and really help you to climb, if I passed danger at night I would run to any store that would be 24 hours, like a market, a poison animal prodded doesn't kill? I think the females are the ones of the kind that really have poison, they don't kill by the strenght but for be dangerous. Probably is painful for them who kills always have regret, in the movie the betrayer was so violent that probably she had betrayed in many lives and remember the shame so she remember to kill before that.
