Saved this just outside the lab he is imprisoned in, then went down the route of freeing him, and returning to Cabot House whereupon he sided against me (perhaps because I had just badmouthed him to Jack) and I had to kill him. This is obviously the least favourable outcome as the other Cabots perish, as does Lorenzo. Then replayed from the save, freed Lorenzo again but helped him kill the Cabots. Still wasn't happy as the guy is clearly insane, but agree with him that his family had leeched off him all this time.
So checked Youtube and the alternative is to not free him and allow him to die from the zeta radiation in his chamber. As reward, Jack gives you some gun modified from the headdress thing, and the other Cabots survive, for now anyway.
I've kept the save and I'm genuinely unsure which path to take. Does Lorenzo stick to his word and keep giving you his serum of immortality? Does it really make any difference to the game? Does he get bored and cause more shenanigans? The safe option I guess is to let him be killed in the chamber, but the Cabots really are a bunch of vampires. Also one of the raiders outside the chamber dropped some serum...is this the same serum? Finally, I think I'd rather Edward Deegan survived, even if his loyalty is a little misplaced.
And yeah I know it's just a game, but I get more out of it if I base my moral decisions on what I might do in the same situations
