Is it possible to be as considerate, decent, helpful, and kind

Although unpractical, it is possible, but only on few specific circunstances.

>I've even noticed I've become much more rash to other people, especially to strangers

I have experienced that myself as well. If you think about it, it is just the natural way of things, given you are exposed to apathetic, selfish and ill natured people daily.
I would not concern myself over it as long as it does not turn you into a selfish bastard.

Helping is fine OP, but be aware that a lot of people out there may not do the same for you or even be grateful for what you do. Help if you want but don't always expect something in return.

This. Don't even expect your best friend to help you return and be extremely wary of people who constantly ask you for help because those are the type of people who won't help you back.

I'm watching Jordan Peterson's latest "Maps of Meaning" and "Personality" courses on youtube, so I'll relay some points.
It wouldn't fuck you up if the character was completely off the wall. Archetypal wise king character is born from real people, real acts of compassion and wisdom that made an impression and have woven themselves into the fabric of culture.
You are already implicitly looking for the principles and insights the character possesses, it's the point of our attraction to fiction. Manifesting those traits demands effort and sacrifice, but those are indivisible from meaningful pursuit, to assign meaning is to label other things meaningless. Also, you shouldn't mistake kindness for harmlessness, which is quite clear with Iroh.

Read "The Generous Gene". It explains why it was evolutionarily valuable for humans to develop an inclination to be good to each other.
