The death of Harambe is clearly (and equally) the fault of all zoos and all their patrons. It’s 100% wrong and cruel to keep living souls caged for profit and the amusement of others. The argument that the zoos are educational is pretty much bogus, they only seem to inspire more animal-incarcerating careers.
Cages are for criminals.
If we truly want to appreciate and respect animals, we’d coexist and leave them in their natural homes and settings and have our children do the same -instead of indoctrinating them to the idea that it’s okay to exploit and abuse them (to death) with Disneyesque smiles plastered on our “… and be sure to stop in at the hamburger stand on your way out!” faces (as we do now).
