Seems like a cultural difference, then. If I was almost killed and woke up in the hospital and the person who did it had the capacity to visit me and apologize but didn't, I'd be tempted to send a strongly worded letter, depending how I felt about the incident. If they did show up, I'd expect to be able to tell the difference between gloating and a sincere apology. And even gloating I might accept if it came with good-faith observation of the principles of reconciliation.
