People do indeed commit heinous acts upon one another. However in a wider scheme of things Satan is the King of this world. Until God returns in might, Satan will direct the events of this world into the deepest recesses of hell. Why do you think culture is taking it's downward flush? It will only get worse before it gets better. Satan will decieve multitudes, as he has already done. Many people find the idea of Satan coordinating world events to be silly, I tell you the truth, if he is the king of this world as the bible states, God has let him have this power.
What you say is somewhat true. But, consider this; God, in letting Satan have the power he wields, also provided humans with the ability to choose between His Word and that of Satan's. We have the choice to follow God's ways or Satan's; we have the consciousness to discern evil from good and turn away from that evil. We can fault no one but ourselves if we fail to follow God's path that he has set before us. Not even Satan has the power to force us into his bidding. We must enter into it will full willingness and cooperation, or turn away from him and toward God.
