Stanley Tucci tried to kill a guy once. And he thinks we ALL have that ability in us, if the circumstances are right.
He says, “You can murder in self-defense. If somebody’s trying to hurt your kid, you’d kill them without a thought. I’ll give you an example. Thirty years ago, I was in Paris with my late wife, and in the middle of the night, this guy appeared on our first-floor hotel room windowsill. My wife screamed, I jumped out of bed naked, and tried to push him off by closing the window. I looked down, wanting to see him dead, but there was nobody there. He got away.”
He went on to say, “The reason I tell you this ridiculous story is that my reptilian brain took over and said: ‘Kill him before he kills you!’ So there you are.”
