I play for fun.
While I can even enjoy my own teams getting pounded, I enjoy it more when my teams kick yours.
I believe bloodbowl is about scoring touchdown rather than killing the other players, but it is often neccessary for people to be removed of the field to enable a touchdown. This is not a bad thing. If they won't go willingly with a block, I'll foul them without remorse.
I beg those who think fouling is bad either not to play me or to whine when they do. It's music to my ears, it's like the highest praise, it makes me feel like I really did well.
Blame it on my style of play, blame it on the dice, blame it on Nuffle, blame it on the Boogie! All this is just a confirmation of the whiner's own lacking skill. Or a celebration of my own.
