I'm curious to know what life lessons we can learn if any from Jodi Arias and Nickolas Cruz.

For those who don't know who these two people are Jodi Arias was found guilty of killing her ex boyfriend Travis Alexander and was sentenced to life in prison without the possibility of parole.

Nickolas Cruz is an American Mass Murderer who was responsible for the shooting at Marjory Stoneman Douglas High School that killed 17 people and injured 17 others.

He was sentenced to 34 life sentences without the possibility of parole.

A few lessons 

• People should be brought up well. In Arias's case, she had been manhandled by her parents and she had emotional issues early on. She even ran from home. An early course of therapy and guidance would have fixed her neediness issues. 
• Bullying needs to be controlled in schools. Bullying is a common pattern observed in most mass shootings unfortunately. 
• Mental health is taken for granted in the country. We need more therapists and effective free therapy. 
• Scanning for mental health issues in schools. 
• Better assessment by law enforcement of any information that appears suspicious such as online threats. A lot of these shooters leave manifestos online. They need to be looked into and monitored to look for real threats. 
• Gun control. A mental Health assessment before selling guns to people. Especially young people at risk shouldn't be owning guns.
