If Jesus was sinless then Yahweh is a sinner!

Think of it Christians brag that Jesus never sinned he was a sinless lamb, he never killed anyone never hurt anyone never cursed anyone etc etc.. If this is the case then Yahweh must be a super Sinner since he was the cause of many violence as found in the Old Testament killing people children's women's animals cursing people torturing people etc etc.. 

Now Christians may say well Jesus was God so God can't be a sinner, then how do you explain the God of the Old Testament was he a different God? You can't have the cake and eat it. Either Jesus was the God of the new and Old Testament which would make him a a violent evil God or he was a human and has nothing to do with the Old Testament ?? Take your pick
