Yes, sometimes I feel that gambling has a negative impact on my life, but I rarely feel it because I'm not very active in gambling due to my busy work schedule. However, the fate of the victim in your story is very concerning. From this story, we can conclude that anything done without proper understanding can ultimately become a time bomb that will cause many disasters in your life.
I believe that the perpetrator was already in a phase of chronic addiction, daring to take another person's life just to satisfy his gambling urges. This means that gambling can indeed cause significant damage to life when handled incorrectly.
