FYI, Bane (with Venom) is stronger than Wolverine. Wolverine cuts the venom supply, Bane is weak. Wolverine is a "stronger" foe that Bane because he doesn't have the weaknesses Bane has. But let's look into your "bind" theory. Once Batman has trapped his enemy, what is his next step? Delivery to Arkum. Arkum releases MULTIPLE villians on what seems like a weekly basis. Batman can trap Wolverine, yes... But his moral obligations prevent him from killing Wolverine. Wolverine has proven tenacious when stalking victims. He would not rest until he killed Bruce Wayne. And Bruce Wayne would not kill Logan. Logan wins due to the "will" and abilities to put his moral dilemmas aside when tracking "foes" such as this case.
