Compassion is, like all other human feelings, immensely unnecesssary. In a world that was entirely gray, compassion exists as a shade of bright pink, something that will point the way to you when the people who wish to see your demise come looking.
Back when he lived among the rest of the Kodiak pride he couldn't understand how anybody would need compassion. Now that he was onboard the Andromeda, and had actually experienced this odd human emotion, he often finds himself wondering how he had ever lived without it. Of course, he would never communicate to the others his discovery. He would let them keep thinking that he didn't need compassion. Because in a world this cruel, letting others know of something that you enjoyed feeling, like love perhaps, often means that you shall soon see that feeling targeted for destruction. If the enjoyable feeling is then destroyed, you are left emotionally vulnerable. If you are left emotionally vulnerable, then you will lose your concentration. If you lose your concentration, then your very existence is in peril. In the end, your life is a short-lived one, all because of- what?- a three second lapse in your emotional control.
No, he would not tell them.
So he spends his spare time looking out at the stars. Andromeda thinks that he is plotting something. He lets her worry because keeping the ship on her virtual toes might just be the sort of thing that would save them all from dying on this fool's quest.
Instead, his thoughts are occupied with longing- longing to go back to the simple days, when he didn't need these inferior emotions. Longing for the days after this journey has ended, when everything will go back to the way it was. Of course, longing too is a relatively useless emotion.
He sighs slightly and returns to maintaining his weapon- anything to escape the tremendous mountain of human emotions threatening to collapse upon his psyche.
