The context of all this, which is missing from your question, is that Britain seized the dreadnoughts at the outbreak of WWI, with the Ottomans firmly in the German camp.

Your last statement seems to indicate that you've made up your mind on the matter, but consider:

• Sultan Osman I (later Agincourt) and Reşad/Reşadiye (later Erin) were bought (from Brazil) and ordered (from scratch) by a Turkish government that was drifting closer to Germany in the prewar period. On the outbreak of war, Churchill ordered the two ships seized to deny their use to Turkey and its potential ally Germany.

• Many in Turkey saw the seizure of the two ships on Aug. 2 as highly dishonorable by the British government. However, the Turkish government had concluded a secret alliance with Germany the same day, which seems in retrospect to validate British fears about the ships being used against Britain or its allies.

• The British fleet at the outbreak of war had a margin of only 7 modern battleships over the German High Seas Fleet. Churchill saw the seizure of the Ottoman ships as vital in securing Britain's naval superiority. Let's assume the Turks get them and sail them straight to Kiel -- Britain's margin in ships suffers basically a four-ship swing overnight.

• Churchill offered to give to Turkey at the end of the war the battleships, fully repaired and refitted, or their value in cash. Additionally, he offered Turkey £1,000 per day to "requisition" the ships, so long as Turkey remained neutral. Parkes' British Battleships 1860–1950 says the offer was ignored, while Massie's Castles of Steel is silent on the matter.

So, was the seizure dishonorable? Maybe. I'd say the secret treaty of alliance with Germany was also fairly dishonorable.

The High Seas Fleet was seen by the British admiralty as posing the only truly existential threat to Britain and its empire on the outbreak of war (hence Churchill's famous comment that John Jellicoe was the only person who could lose the war in an afternoon). I don't think it mattered what country those ships were intended for, and especially given that they were about to be sold to a potential enemy -- they were going to be seized or at least diverted from Turkey.

Perhaps better to classify both as artifacts of realpolitik and leave it at that?
