I'm not sure what, if anything, the Kenyan embassy could do. I would guess they could file a formal complaint with the government that one of their citizens had been held in an abusive and negligent snake pit, where he felt compelled to take action to free himself - and now was being charged with a crime as a result.
Also, maybe, they could offer to send him home to live with relatives in Kenya. I know many a TB kid would be delighted if the US embassy in Jamaica offered as much.
