Las Vegas Mass Murdering

The Las Vegas mass murdering was a really scary moment for the people that were in that concert. thinking that you're there to have a fun time in a concert but never expected for a shooting to go on and ended 58 lives and left atleast 500 injured on sunday night. The gunman shooted from a 32nd floor of a las vegas hotel. Paddock had 12 of his rifles with a legal device called a bump of firestock.  what i ask myself is that why would he do that to those poor people that had 0 fault that he wanted to kill himself. if he really wanted to kill someone he shouldve killed himself not go and harm other people because he feels like he doesnt want to live. in my opinion they should have more supervison not only in hotels but in other places mostly right now that were in a really cruel place where other people don't care what they do to others. he should've gone to therapy to get help because now theirs places where they could help you not just go and shoot all these innocent people. i feel like now these you can't go out without thinking that theirs someone out there that wants to harm people.
