Odo vs. Spock and Data

[Captain McBain]

Would Odo die for the crew of DS9, if that was the only option to save them, as Spock and Data did for their respective crews, or no?

[R. Star]

I could see him doing this for Kira specificly without question. The rest of the crew..? I dunno.

This is not a thing to be despised or looked down upon. One can never truly know until the man and the hour meet.

For Odo, I think it would depend somewhat on when in the series you speak of. While I think in later seasons maybe 4-7 he'd do whatever it took to save any of the crew, in seasons 1-3 he was still distrustful of the starfleet crew, albeit to a lesser extent as time went on. He put himself at risk for them many times during those seasons, but it was never a black and white, you do this and you die, type of situation.
