Jin made one massive mistake. You can only train a tiny portion of the animals there, and even fewer would retain that training. One guy trying to tame all wildlife is doomed to fail, even if he wins the election. This isn't a video game where taming is a simple process of pressing a button and waiting a few seconds.
Also, King is the best side character. Calls his girlfriend lewd on live TV for all to hear, brazenly admits that he has the strength to control his lust, and drops the hard truths on Jin.
