Chibi Halo
He was definitely flaunting off the fact that he he has the means and connections to get things within the city in order to butter up Korra. The fact that he uses his political influence as a means to get what he wants makes him more of a concern than Amon. Even without his bending his position on the council and the connections he has among the well to do has a far more reaching grasp than the fact that he can bend water. A lot of people can bend water but only two of them are members of the council for the city. The fact that he's connected to captains of industry means he can push those with money to back anything he likes and can use Republic City's one percent to further whatever goals he has. Amon is all talk with some skill and knows how to play on people's fears to get what he wants but in the end even he can't stand up against the might of the corporate machine and the all mighty Yuan.
We'll have to agree to disagree with that, I think Tarrlok downplays his power and influence in public to gain more of it, which is why Tenzin's always so annoyed with him because he can see through that charade. He tries to be humble and servile so he doesn't seem suspicious, and I don't think bribery counts as flaunting when the purpose is not necessarily to show off but to appeal to the target's sense of greed, or pride.
As for the rest, all good points but I don't really know what that has to do with what I've been saying, really. I don't think I've ever even mentioned his waterbending... I understand why he wants to go after Amon, it's a nice feather in his cap to take down a rebel and that prestige would allow him to push for god knows what, but it's not an incredibly politically sound maneuver. In the eyes of the
public I think Amon is far more popular than Tarrlok is at the moment. For one thing Amon's actually done something about the bender triads while Tarrlok is picking a fight with ordinary people, just ramming home the point that benders will not give up their power without a fight and does not give one single damn about what the people want, and my next post was clarifying that. This is, as I said, assuming that the populace have any say in choosing political leaders.
It will certainly make him a golden boy among the city's elite, but I would add that Amon is certainly not any less frightening with the non-bending population at his back. In the end, the people make the government, and with sufficient force they can tear it down. Amon's influence can start a civil war, and I personally believe Amon is more immediately capable of plunging the city into anarchy than Tarrlok is of... well, being a tyrant or whatever he's after.
And like I said before, even taking in all those factors I'd prefer not to see Tarrlok upgraded to the main antagonist because I enjoy him more as a chaotic neutral, working for himself and only for himself, rather than have some evil machinations at work. If he's just after power for power's sake I can't say I'm too bothered by that, to be honest.
