I have come across a range of players. I notice that some people are very hard core loyal to a particular alliance. Others have a preference and I would guess yet others are fairly indifferent.
It did occur to me that from the perspective of your character, your presence is a matter of getting randomly dumped in the world after escaping Coldharbour. The base game dumps you in an area based on the alliance that matches your race. There is likely to be some attachment to fighting with your countrymen/country women. It gets a bit more complicated with any race / any alliance and playing as an Imperial. You may be playing outside your characters race. As a player you chose to put a given character in an alliance. This implies the character should be loyal to an Alliance but from a role playing perspective there is scope for a character having to survive in a faction from whom they are indifferent or actively hostile.
Even NPCs can vary in attitude. A Darien / Razum-dar / Captain Rana type is deeply invested in the success of their alliance. Someone line Jakarn seems focused on selfish motives and cares about the alliance in so far as it affects him but seems unlikely to risk his life or make big sacrifices for it. Lakhazga gro-Rimat feels so badly about how she is treated by the Covenant that she is happy to defect to the Altmeri Dominion.
How about you and your characters? There isn't any option made available to directly perform actions to betray the alliance you are in. This may make it difficult to have scope for role playing being hostility / indifference to an alliance beyond refusing to do any alliance oriented quests.
