Evil is so real that it cost god´s son his life

I have asked myself hundreds of times why God sometimes allows evil to flourish- and I don't have the full answer to that question. Evil is real, however,if we ignore it there is more danger ahead. Evil is so real that it cost God's Son His life.
But, I do know this: Even in life's darkest hours," God is our refuge and our strength". Not money, not military might, not diplomacy, not human cleverness- but God. Is God your refuge and strength? He can be, as you open your heart and life to Jesus Christ.
Psalm 46:1-3 (CSB)
God is our refuge and strength, a helper who is always found in times of trouble.  Therefore we will not be afraid, though the earth trembles and the mountains topple into the depths of the seas,  though its waters roar and foam and the mountains quake with its turmoil.Selah
