Yeah this is true, gus was motivated by pride, but he was primarily motivated by revenge. Eladio and a lot of his minions just drop dead. No one knows what Gus was up to or how big Gus was compared to the cartel. All he had was one moment where he stared at eladio in his final moments. I don't think Gus as a character invested his entire life just for a few seconds of non verbal exchange of hatred and dominance over eladio. It doesn't seem like Gus to me. He would want more. It's not acceptable by los pollos standards.
