I can respect that, but ScareBeast never made sense in the first place, and becoming a Lantern would have him remain the same psychological-wise and yet expand his options massively to planetary scale. Now he just seems like a generic trial villain or crowd-cameo villain.
And it would just be cool to see him wield a yellow-light scythe and have a Batvillain fight the GLC after Emoboy-Prime and Cyborg-Superman.
