In my opinion it is one of the saddest dog deaths I've ever seen. He is not only killed, he is abused first. I absolutely hate this movie with a passion and wish I had never watched it.
Two men are forced to engage in a sexual act or be killed, in front of a crowd of hostages. They do end up changing their minds about how they feel and consent halfway through the act, but the initial set up might be upsetting for some. Also, a man places his severed dick in his employee's hand against her consent.
