Greetings Zafreen.
Giving everyone the "choice" is a mercy from Him.
How can a Merciful GOD force His creation to accept anything they may not want ,even if one argues nobody likes to"suffer" ?
The Merciful has given us life, Is it better to exist than not to exist?
The Merciful has given us freedom of choice, should He not let us make that choice?
The Merciful has provided everything we require on this " blessed" Earth, Are we not lucky to have water,oxygen,food...etc?
Once you make the right choice you may attain more mercy from Him?
For example:[2:155-157],[4:175], [6:16].[7:156-157],[7:204],[33:43]...
Suffering is caused by us, people taking the wrong decisions,making the wrong choices ...etc.
Remember more mercy is open to everyone:
[Qoran 2:160] As for those who repent, reform, and proclaim, I redeem them. I am the Redeemer, Most Merciful.
GOD bless you.
Peace.
