And that's it - the 'evolutionary advantage' if you like. Putting aside their actual behaviour & focussing on their literature, we have to say that the AngloSaxons held ofermod in higher esteem than the kind of 'cunning', logical behaviour in the examples you gave of actual battles. I'm not sure if there are songs or poems about Harold's or Alfred's exploits, but I suspect if there were they would depict them as displaying reckless courage over tactical cunning.

Eomer reacted in a passion during a period of intense stress. Such things are a natural part of combat. This in no way indicates that Rohan had a cultural policy of foolhardy battle-mania wildly driven on by unchecked pride. As I noted above, Theoden (who died in a way befitting a hero of that mode) never displayed that type of behavior. If he had he would have bravely charged the army guarding the road rather than chicken-heartedly going through Druadan Forest

Well, I suspect that if Theoden had 'bravely charged the army guarding the road rather than chicken-heartedly going through Druadan Forest' (& won) he would have been held in even higher esteem than he was, & if his forces had been totalled by Druadan ambush in the forest, he would have been condemned for his 'cowardice' in refusing battle on the road.

But I can only cite Faramir's words to Frodo (don't have the quote to hand) about the Rohirrim being 'middle men' who held feats of arms & martial glory as things to be admired, & how even the Gondorians esteemed such things above music & lore.

Once they were there they had little choice but to continue their little diversion on to the end. They would all have been killed anyway, in very unpleasant ways if they had surrendered.

I don't see this - Sauron had offered them terms of surrender - he wanted control, he wanted slaves, & he wanted that as quickly & easily as possible. I think if they had surrendered he would have accepted that, if for no other reason than that if he had taken their surender & then slaughtered them then everyone else in the west would have fought to the death, & it could have taken his years to achieve victory - indeed, it would have increased his chances of ultimate defeat - even with the Ring we can't be sure that he could hold back the whole of the people of the West, if they were certain that he would slaughter them if they surrendered.
