I recommend you read "Religion of the Apostles" by Stephen De Young. He explains the common misconceptions of the early Israelite beliefs. The "Gods" are lesser divine beings that were meant to protect the 70 tribes after the Tower of Babel fell. The deities rebelled against God and led the nations astray and were worshipped. The tribe of Israel worshipped the God of "Most high" which is the one true God above all divine beings. So they aren't henotheistic because there is only one God. The term "Gods" was used because they were divine beings but they were created whereas God the Father is not. Everything proceeds from him.
A great podcast that explains evil and suffering is "Whole Counsel of God" with the same guy. In short, suffering is unavoidable because man falls from Eden after sinning and the consequence of sin is death. Making death the consequence is a mercy because man can become sanctified during his life and through death re-enter the kingdom of God. Consequently suffering draws people closer to God than anything else.
I'm not a theologian and wrote this on my phone but that's my quick recap. The book is way more thorough of course.
Thanks to schismatics there are almost as many different Christian perspectives as there are Christians. Protestantism in particular constantly innovates and separates creating a lot of confusion, strife and (based on your comment) vitriol from those who rightfully interpret what they are hearing as word games and manipulation (no matter how well intentioned).
I encourage you to read Orthodox exegesis of scripture. There is some differing theological opinion in some of the writings of the church fathers but the core tenets of Orthodox Christianity are not up for debate and remain unchanged for at least 1200 years.
