While these very points were instrumental in my move to atheism/secularism, your statement is a bit flawed... It does not prove god is not real, but it does prove that the idea of the 'god of love' whose every action is motivated by love is not real. In the bible, the devil is a pussycat compared to YHVH.
I would also argue your last point, if only in the way you worded it. You said, " why does God INSIST on letting this evil subsist on and on and on, creating more pain and suffering each day?" Are you saying the world's evil is getting worse, creating more human suffering as a result? You may want to reconsider your position on that... "Evil" isn't to blame for nearly as many problems as the WT would have us believe. As a whole, humanity's suffering decreases a little everyday if anything.
