Free will is not a gift from God, but rather it is a commodity that is purchased with another commodity, responsibility. Only those that are mature enough to responsibly exercise free will are truly free. Those that aren't mature enough are led down an evil path giving up their free will in the process.
That's called sin.
Sin begets more sin and puts one well and truly down the path of no return.
Maybe.
There is hope and God's love. I pray that those responsible for the deaths of children and other innocents in the recent Russian hostage crisis will be able to reverse their steps along the path they believed to be paved with good intentions. And I pray that those left behind have comfort physically, emotionally, and spiritually. An additional prayer is that this experience helps us all mature in our free will that we can be responsible and loving grown-up children of God.
