A very poor post and exposes your limited understanding of the situation
There was no arrogance or over confidence or cockiness involved in Hood's lack of a deep Warspite / Renown style deep refit - it was needed, the British had known pretty much from her launch that she was obsolete but in the 20s and early 30s very little could challenge her no one was building new fast Battleships at the time.
The British wanted to give Hood a deep refit in the late 30s (they wanted to give all of their old ships a deep refit) but this was continuously delayed due to the need to have her at sea - i.e. the Neutrality patrol around Spain (its a tough job being the worlds policeman) and then as things went south in 39 she and the other Battle Cruisers Repulse / Renown were needed to respond to the Twins and the impending launch of the Bismarck until such a time as the KGVs could replace her and guarantee a 2 : 1 advantage as the existing 12 British Battleships QEs, Revenges and Nelrods, would have been too slow to catch them.
As for scrapping Warspite - the successful Deep refit she got was subsequently used on 2 of her Sisters and HMS Renown - making them very effective ships so Im not sure what your point is?
