Well, I guess we can look at the options and criteria and move on from there. I will make the assumption that Jing can handle either fight just fine. I'm positive Jing can take on the abbot by refusing to use his own dangerous moves (Jing is really good at the lack-of-self-preservation and the extreme-willpower things) and the 18 bronze arhat formation can always be defeated with Wuxiang Qiankun, if it comes to it. That lets us pin all of it on Xuxian, who indeed doubts his own abilities to pass both challenges.
The criteria is self-control. Xuxian is not allowed to hurt anyone, whether by accident or by aggression.
The skill is known to make people more careless and aggressive.
The two challenges are:
- 18 Bronze Arhat Formation. Defeat everyone without injuring a single person.
- Face the Abbot in single combat. Either defeat him without injuring him or (and treave says this is an important point) pass by restraining oneself from using the skill enough to lose the fight rather than use it.
Additional detail: they (both Arhats and the Abbot) will be setting the bar pretty high and pushing the limits of what they're allowed to do.
Now, avoiding accidents is a question of skill.
Self-control (avoiding aggression) is a question of humility and/or willpower.
If he has high skill and high self-control, either option will work for him. We know one of the A options will fail, though.
If he has weak skill and weak self-control, neither option will work for him. We know one of the A options will succeed, though.
If he has weak skill and high self-control, then facing the abbot is better because he can overcome that trial by sheer willpower or refusal to use one's strongest abilities. Both options will pressure him, but he has to win against the 18 bronze arhats, while he can afford to lose to the abbot.
If he has high skill and weak self-control, then either he will probably lose in both cases (because presumably they really intend on stressing and provoking him) or he might be able to win against just the 18 Bronze Arhats because as weaker individuals they provoke a less aggressive response.
So far we know the following about Xuxian's mistakes:
He has accidentally injured a fellow student. This could be aggression or error.
He has accidentally injured the abbot. This was fear and panic.
We also know the following about Xuxian's humility and/or willpower:
He was panicking and fiercely apologizing to everyone he injured at Tufan.
He returned to Shaolin to receive his punishment.
Additional detail:
Xuxian spared all his enemies on the way to Shaolin.
It is my impression that Xuxian is someone who fears really hurting other people and would thus sooner back down or run away than he would risk killing his enemies. I think it's also safe to say that Xuxian's skill, while improved, isn't extremely solid either. In that case, we have to trust his willpower and humility are sufficient.
So I think Xuxian is better off facing the abbot.
