Hermione could feel some sympathy for the man. She wasn't without her own guilt after all. If his younger brother hadn't crossed her path that day so many years earlier, he might still be alive. Probably not though. Oliver Wood had a habit of getting involved in lost causes. Part of being a Gryffindor, no doubt. It was likely that if he'd managed to get out of the trap set by Antonin, he would have simply been killed by another Death Eater on another day. Wannabe heroes like him didn't have a long life expectancy in their world.
