I don't know anything about the context here except that Topeng Monyet — forcing macaques to wear human clothes and ride bicycles for entertainment — is a somewhat-common practice in Jakarta that's also (understandably) frowned upon by the animal rights community.
When I frame it that way, I can kind of understand why this badass monkey is so pissed.
(Just a heads-up: it's a strong, scary monkey going after a kid.)
