I think many of the decisions you make that are good decisions are helped by your friends and family. When people act alone or without support, they tend to make bad decisions. (Not to say this is always the case, just something I’ve noticed and felt in myself - I make bad decisions when I feel alone)
The first mistake he made was not seeking assistance after the stabbing incident. Either he didn’t trust anyone or he simply didn’t have anyone he could turn to to take him in. Many people would be able to go back to their parents or stay with a friend after something like that, but he felt that going homeless was the only option.
Even if I wanted to go homeless, I can think of a number of people who would literally drag me off the street and in to their house. Where was that for this person?
Surgery is a decision that an individual cannot make alone, it’s too overwhelming, you need support to get through that.
