I would say that it depends on the circumstances.
As an example;Flash Thompson was just a bully in the first years,but he was wrote as more complicated fellow than that and eventually,he became Peter's friend.Him joining the army and becoming Venom may sound weird out of context,but it was executed very well.

Most of these characters just need an right story to appear.
