I would help him. I would try my best to help anyone that was hurt and dying, I don't care who they are or what color they are. Besides, I'm a sucker for a man in a uniform. Kidding, kidding.
I do think that the KKK is a horrible organization, just because of the history behind it, they teach hate and that's terrible.
On a side note, my great grandad was in the KKK, noone hold this against me. Thankfully the trend did not continue through the family. But his time there ended after he was tarred and feathered and drug through the streets by his KKK brothers because he was caught beating his wife. So, atleast they do one good thing, lol. Now, would I go help my great grandad after this, hmmm, probably, I hate to see people hurting, but I'd beat the hell out of him while he was down first!
