You are TOTALLY CONFUSED,(no offense),,cause you didn't read the last Revelation from God (Holy Quran),,and thats why missing very big part of the truth,,! plus that unfortunately the Bible (Torah + Gospel) is corrupted and been changed by lots of people in many ages,,so you really need to know that the MAIN purpose from this WHOLE first life is how God test us a FAIR TEST,,! and its we who chose what to do and to make this world (First life) good or bad !
i agree with you how humans made lots of bad things and the main reason for all the suffering for others,,but we cannot Blame God for this as God himself warned us NOT TO DO THIS !! and how we all suppose to be Kind and WORSHIP him which mean to obey him and his laws which is all about being Kind and helpful and true believer ! so as we both know and everyone ,, all this horrible things happen cause of us !! as Humans,!
God gave us the free will and we all suppose to use it in the right direction,,thats why in there hereafter there is immortal life in paradise or in hell according to our record of deeds ! so Kindly,,calm down,,and dont blame your Generous Lord,,our Creator who is the only reason for all the NICE things and all the evil and bad things is from us ! not to blame God for it,,honestly this even dont make any sense..just being Honest with you.
