How do you know all this 
There has been so many examples from history.
Christians being fed to the lions, Jesus being beaten and whipped by the romans because his own people the jews abandoned him, Mother Teresa feeding the poor and destitute, innocent babies being murdered, so many examples.
Do you actually think a loving God wants to see suffering especially for people that love him? The answer is no.
He gave mankind free will to either choose the right or wrong thing. We have the choice to either stop the wrongs or right the wrongs.
If God took away our free will, He wouldnt be a God of love but a god of enslavement.
