SBS is an Australian TV channel. Anime, much like any other movies or TV shows, have different genres, some action, or horror, or slice of life, etc. Believe it or not, what you described in this particular anime, can and does happen. It just hasn't been seen in your life, but it can happen, which is what I love about anime. Not everything is slice of life, butterflies and rainbows. As Koby said, if you don't like that type of anime, then simply don't watch it. If all anime was the same, then it would be repetitive.
