Not as difficult as all that, If I offer you ice cream and know you like chocolate, it doesn't make a difference what other flavors are available. You are determined to get chocolate. Your decision is known and there are no other choices because of one's chocolate affinity. I don't like chocolate. My desire dictates what I eat. You say I'm locked into vanilla. You may be right, but I'd have it no other way and don't mind at all that I am a slave to my predictability that gives God and anyone buying me a dessert a certian foreknowledge that constrains me to that choice.
God made my tastebuds the particular way they are and I wonder if He didn't make me a vanilla-lover in the first place. "Oh no! I'm a vanilla robot!!!" ('Please' and 'so what?'). If I'm without LFW (and I believe I am) it dimishes my self-importance which is where I desire to be. That desire is a fundamental impetous for believing as I do.
Or we could take that to its full measure and say "God made me want to go to to hell" and "God made you want to go to heaven."
We should care about those hell bound, it is just their god given preference...
