The man known as the Son of Sam killer - who shot and killed six people during a year-long spree in New York City in the 1970s - says "society has to take the glory out of guns".
David Berkowitz lamented the recent mass shootings that left dozens dead in a cinema in Aurora, Colorado, and a Sikh temple in Oak Creek, Wisconsin.
Berkowitz, a born-again Christian, spoke to the Daily News from Sullivan County Correctional Facility in New York, the maximum-security prison where he is serving six consecutive 25-years-to-life sentences.
He said: "I'm looking beyond gun control. That's for the legislators to wrangle with.
"My hope is just that young people would understand just how terrible this violence is. When they use a gun against someone else, they ruin their lives too. It's not worth it."
Berkowitz, dubbed "the .44 Calibre Killer" for the gun he used, was arrested at his home on August 10 1977, after he terrorised New York City over 13 months, killing six people and shooting seven others.
Berkowitz later claimed his neighbour's dog ordered him to carry out the murders.
The 59-year-old appears to have undergone a spiritual transformation, saying his killing spree came at a time when he was "lost, tormented and confused".
Last summer, Berkowitz said he has no interest in seeking parole. He told the Daily News it is the "proper road to take" to spare the victims' families further pain.
He said: "I continue to pray for the victims of my crimes. I do wish them the best in life. But I'm sure the pain will never end for them. I regret that."
