Issue being discussed: A man killed his elder brother after a heated argument and is now arrested.
General observations about issue discussed: They are siblings and I think kinship is more important than what they are arguing about. We should learn to calm down and talk things over and not resort to violence as it will never solve the problem.
How the writer approaches this issue: What this man did was really cruel and terrifying. It is foolish to be violent over an argument. One should learn how to control our emotions and not do foolish things in a moment of folly. I think if they have family problems, they should sit down and talk about it and not do serious things like resorting to kill the other party. This is a serious consequence and I'm sure he would regret it for rest of his life as they are brothers after all.
Relating to singapore context: I think this man would probably get a death sentence or be sentenced jail for his whole life.
