Indeed tragic. In a fit of anger, a life is lost. If only Tao has dharma and is able to control his emotions and anger, such tragic incident would not have occurred. I conclude that Tao is not a strong person and maybe a coward and can’t take pressure. If he is strong enough, he should say No and dropped all the shopping bags and leave his girlfriend. Why jump to death? He is also a selfish person, not thinking of how his family members and loved ones will be affected by his death.
