Did Krishna feel confused about which pure devotee to support – Arjuna or Bhishma?

So did Krishna ever feel confused about whom to support that two of his pure devotees arjuna and vishnu are fighting with each other actually Krishna supported both although externally it appears that Krishna helped arjuna to win but Krishna helped Bhishma to win also Bhishma's death was an eternal victory and not only that even at that particular point Bhishma's vow was either I will kill Arjuna or I will make Krishna raise his weapon so what did Krishna do Krishna ensured that Bhishma's word was held true and he held the word true how? by raising a weapon so in that sense Krishna by raising the weapon not only protected Arjuna's life he also protected Bhishma's word so that way actually Krishna worked for both his pure devotees but because Bhishma was fighting on the side of dharma at that particular time so he had to die Arjuna was fighting on the side of dharma Krishna had come to establish dharma so Krishna helped Arjuna win so in the immediate context of the war it may appear as if Krishna favoured Arjuna and not Bhishma but from the ultimate perspective he blessed both, he supported both.
