I was leaving this thread, since it's gone way beyond the question of Surya/Durvasa, but I'll answer this one, since the very premise is mistaken.
Karna approached Drona for the Brahmashira knowledge after Drona had given it to Arjun: there is nothing in Shanti parva that suggests otherwise. Drona said nothing about readiness - his only criteria was caste. He also said nothing about who deserves to have it or who doesn't. Nothing is mentioned about whether he taught that to Yudisthir or Duryodhan, for example.
My problem w/ your argument here is giving Drona the benefit of the doubt by assuming that he had more befitting criteria in judging who to teach this weapon. If one goes not by caste but by temperament, how was Karna a less suitable recipient than Ashwatthama, who was taught the weapon, once he saw that Arjun had received it? Both were jealous of Arjun, but Ashwatthama was worse.
The reason Karna wanted this was that Drona had taught it to Arjun. Since Karna wanted to be superior to Arjun, he obviously needed this, and hence his pursuit to Parashurama. As a warrior, your job is to gain superiority over your enemy. With Arjun having received this, there is no way that Karna could just let it go.
Here is a thought experiment - if Parashurama hadn't cursed Karna w/ forgetting the mantra for that weapon, you can bet that just like b/w Ashwatthama-Arjun, Karna & Arjun's brahmashiras would have collided, and both would have been asked to recall each. Now, Karna may have been capable of doing it - or not. But here's my question - if he couldn't recall it and had to redirect it instead, do you think that he would have redirected it at the wombs of the Pandava womenfolk?
I don't. So if on temperament grounds Ashwatthama was good enough to get it, so was Karna.
Incidentally, my real opinion on this one is that either Parashurama or Drona was at fault. Drona needn't have taught that to anyone, and neither have Parashurama. They didn't need to give their pupils weapons w/ which to destroy the entire earth, which is what the Brahmashira was.
Had Drona, or better yet Parashurama, not given it to anyone, things would have been a lot better.
Anyway, this is my last post in this thread - we can take this discussion to the D&D thread, or create another thread instead.
