From mankind's perspective, these things are bad. So are hungry wolves and bears if you're in the woods with them. God's ways are not our ways. We will never understand everything He allows.
Agreed, but what does that have to do with the concept of intelligent design?
You see, intelligent design is being put forward as an alternative scientific theory to the theory of evolution. So I am trying to explore this question more in a scientific or philosophical sense than in a religious sense.
