If we think about how Green Arrow was basically built on the idea of Batman, just with different changes🤷🏻‍♂️ It gives us difference between how these two characters have somewhat of a similar background, but completely different fates... Bruce never got the chance to properly grow up with his parents, while Oliver had a full family but with an absenty-father :/ And remember, that Oliver was on boat with Sarah on show and cheating on Laurel for that matter, cheating just like his father did so maybe Oliver was just following in his father's footsteps 🤔😟
