No, that's just asking too much in a situation like that. A life and death struggle with a full grown tiger? Unless you have major super-powers, you couldn't expect Cap to take a chance like that. If the tiger wriggles around, it's a disembowelment and the next issue would be retitled THE VISION or something.
It's like the cliche of the cowboy shooting the gun out of the bad guy's hand, so as not to hurt him. It's asking too much.
