If Allah(God) merciful then why killings etc are happening?
Indeed Allah is merciful but this life is a test; Allah knows what people are doing and what in their hearts 
He is just giving them time to return but when He will catch them then He will never let them go 
He is giving time just because He loves us 
There is in Qur'an if Allah caching people when they do sins then there will be no one 
Just ask one question from heart
Are we so innocent?
If we are sinful then why we are saying Allah should catch others,why we have double standard 
You are denying Allah but He is giving you time everyday you see many posts and things these are invitations from Allah but you deny them 
But at the end you will see the result and that time will be too late
