Its not rage bait. There has to be a reason he's been in so many storylines. Seriously, how many times has he been there to mess things up. How many books has he been in where he did the worst thing at the time but somehow escapes with no consequences. He even got promotions. Since book 1 he's been there.
1. Donald Morgan, dead
2. Murphy, dead
3. Bianca, dead
4. Carmichael, dead
5. Susan, dead
6. Marcone is alive.
Most of the characters in that book are dead. The rest have at some point helped Harry at some point. There has to be a reason. Do I despise Rudy? He might be one of my least favorite characters EVER.
