He was looking for easy targets. People who wouldn’t dream of fighting back.
This man was an example of how holding onto ancient superstitions can poison society in the modern age. He was raised to believe that being comfortable with his own sexuality was a disgrace and it tormented him to such a degree that he wanted to die.
Killing himself would have revealed that he was weak and he was afraid that everyone he loved, and whose approval he wanted most, would find out that he was gay. This would mean that not only was he weak, he would be a disgrace. He would rather be reviled as a villain by the entire world than accept his sexuality and face his family and the rest of society. So this was his way of going out in a blaze of glory.
Societies around the planet have always evolved at very different paces. I fear we have a long way to go before these types of issues are resolved.
On some level, I question whether people who hold to religious beliefs where an anthropomorphic deity watches over them every second of every day and judging their actions, should be permitted to participate freely in society without a tracking system and remote controlled shock collar.
