Nobody in the last 200 years has been injured or killed by a wild bison or bear or hippo who did not deserve it completely.
You are getting way ahead of yourself with that statement. A lot of injuries and deaths are from unexpected contact and can happen even when people take precautions.
But as far as those two idiots, I would not render first aid if they got themselves gored by those bisons in my presence. One has no legal duty to respond and it simply would not be my problem because I do not want to have dreams or recollections of seeing someone up close in that bad condition or want to get someone else's blood on me. At bottom, I do not want the blood of others on me period, and I am not going to voluntarily make it happen due to the preventable stupidity of someone else.
