Because sin is part of the world therefore there is going to be evil. If there was no sin, there would be no evil. The decision of Adam and Eve to participate in the sin of the devil by rebelling against the only ordinance created the possibility for evil to happen to everyone and everything because natural evil entered and also because of Judgement. It's a tough thing to hear, but basically the world is broken and like Romans says it's constantly moving until the redemption. I feel sad and hurt when I hear about the losses of people and animals because it demonstrates how broken life is, but simultaneously I want to rejoice in that Christ has made a way to redeem the creation and if we just listen it will work out. Sadly, this is not true because not everyone responds, I am praising God he let me respond and blessed me with grace and mercy. I wish more could, I hope and pray for the people who can really make a difference in society to become extravagant and crazy mercenary Christians.
God bless you.
