People want God to prevent massacres of the innocent or horrendous disasters, if He stepped in and did that and wanted to step in and control other areas how would people feel?

Several times over the past 24hrs I hear how could God let that happen to those little kids, and at Christmas time to boot; why did He not put a stop to it before it happened. Why is it people want God to come to the rescue and prevent a disaster or save people like children from a calamity but they don’t want God to take a part in any other part of their lives? What if God would have stepped in and prevented that massacre but then decided there were other areas He needed to step into and if people did not obey disaster would fall on this nation, would people see that as an even trade off?
