Why Does God Allow Tragedy To Happen?

Does God send bad things to people?
The Bible says ‘No.’

jeremiah 29-11
God isn’t the cause of tragedy. God doesn’t send all of those unfortunate events into the world. Whatever may be in this case, God is definitely the Healer; the One who grieves with us, cries with us and shares our pain caused by disaster.

So if God doesn’t bring devastation into one’s life, then who or what does?
