I go down to his little chamber, determined to put an end to him... and there he is in his little tube. I unseal him, and starts yelling at me about all the time, preparation, and work towards Good.. wasted. I tell him I'll let him live and just disconnect him, he tells me he'd rather die.
It broke my heart. I quite (didn't save) and don't know what to do now...
I understand that House, NCR and the Legion are all guided by different philosophies. You decide whom you wish to support (if any) based upon whose philosophy you wish to support.
House seemed to have it all figured out (space colonization in a century, WHAT?!), and the NCR is... well, trying to pick up the pieces and reform a democratic government. Caesar's philosophy is well enough, but his practices are abominable. Can't do it.
However, House wants me to eliminate the Brotherhood... and this is still a sticking point. Can't do it.
I'm forced to, however heartbreaking it is, stop Odo. I don't know whether I'll kill him or not though, as (I think) keeping him alive aids the Followers via that bug you plant.
