Based purely on reading the bible while trying to ignore WT influence (which after almost 40 yrs is tough) I came to the conclusion that Jehovah of the OT is in fact a loving god to people he choose's to be namely the israelites. However he encouraged the slaughter of countless innocent "pagans".
As for Jesus... honestly Jesus is god almighty. The tetragrammaton isn't found much in the NT because its there in the meaning of Jesus name "YHVH is salvation". This point though I still go back and forth about though since the WT's argument for Jesus being only the son is logical but only up to the point where you realize that they changed the meaning of some scriptures by adding words such as [other] , a god, etc. when referring to Jesus. Also they aren't consistent with their translation of the greek word for lord to Jehovah in the NT as they leave it out in a few places where it the context refers to Jesus. Its all very confusing but I tend to believe that the WT is trying to cover something up to protect their doctrines. Somethings fishy..
