[SHIELD/MCU] Why does a secret spy organization like Hydra have a logo and why do they put it on everything?

Symbolism traditionally inspires. Red White and Blue is synonymous with America and it's ideals, the swastika was used as a propaganda tool for the Nazi's, Crosses are generally used for Christian based faiths. Hydra does it for the same reason. To know you shouldn't be screwing with them.
