hmm well I believe you are trying to put all the books that compile the bible into one to try to understand God. You must remember the bible was composite of many books
It has instructions to it . It says to test prophets and spirits. How you do this? Well you cant test by what John said because you wouldn't be able to test before Jesus. So test it By saying "Does its writting come back to God?" Well lets test some as an example the book Revelation hmm that's a book written by another guy named John about a dream he had. Hmmm well guess you can make your own conclusion on that one Knowing that the word evil dint exist in Aramaic in Jesus time. Does claiming to kill another creation of God in the name of God comes back to God? These are all questions the Bible instructs you ask. Also try to translate Things like what Jesus spoke your self so you don't get someone else's point of view on the translations. You will find words that explains a lot of questions
But remember this was a book compiled by someone making decisions on what to keep or what to take out and how to translate it. Now about the question is God a murderer? Hmm the bible says "This body is a seed for your next body". Well everyone has different paths they take to reach the next body. As far as emotions such as suffering well its there to guide you. You don't like to see people suffer. Hints you, try to change that action. It hurts to put your hand over a flame, It hints you not to put your hand over a flame.
Also very important any bible from any religion you read it tells you that we are the care takers of all other life. So do try to take care of the one thing all life have in common, the valuable DNA. Do try to make sure that it will keep on surviving.
