You take away guns, killing will increase with sharp objects. You take away sharp objects, killing will increase with rocks, sticks, etc. Some how you manage to take away even all that, killing will increase with the mere usage of a perpetrator's hands or ANY inanimate object in his/her proximity. The problem is "evil" fueled with high levels of wrath/rage/hate, NOT inanimate objects.

The solution is abstaining from vices like wrath/rage/hate and incorporating virtues like love/respect/patience/righteousness into your daily lives.

Even better, is accepting Jesus Christ into your lives and your heart as your Lord and Savior. Praying everyday to God through Jesus Christ to have these virtues instilled in you helps you and some of those around you.

Romans 8:31 What shall we then say to these things? If God be for us, who can be against us?
