We were created to do good. We do not the features of the wild beasts and carnivores because God did not create us to be like them. We do have the features of harmful animals because God didn't make us to be harmful and destructive.
When we consider ourselves, we will observe that we were not created to be harmful. We were created to do good. Our body parts were not design to hurt people. We are not to be harmful to one another. We were made to be loving and to do good at all times.
Many times when we walked away from the purpose of God for our lives, that is when people will used harmful objects like iron, knife, gun, etc to cause harm to our fellow humans. We were not formed to hurt each other.
It is people who walk outside God's commandments that engage themselves in the wrong things. Such people become terrors to others. They explore deadly materials and use them against others. We were not created by God to do bad to others. We are His workmanship created in Christ Jesus unto good works. When we understand this truth we will use our whole being for good.
