Undertaker's beating

Now, usually the Undertaker's the attacker, but over memorial day weekend, the Undertaker suffered such a beating that it put him in an unresponsive state, and now his biological brother, Kane is seeking vengeance on his brother's attacker and is acting as Judge, jury, and plaintiff, and will probably not be very how should I say this...forgiving/nice to that person and will unleash his full wrath on them.
