The message of homeboys

The message of the book homeboys by Alan Lawrence sitomer is that revenge is always not the answer. The reason I picked this theme is because the teddy wanted to kill the guy who killed his sister but didn't want to. The guy said "why aint you icin me?" He replied back "I don't want revenge". Revenge wasn't the key for him. This was on page 264. This proves that teddy only wanted his sister back not the guy killed.
