Should i Kill Or Free Lorenzo Cabot?


I picked up the side quest “The Secret of Cabot House” and I have found it really interesting. I am at the end of it now and I have located the Lorenzo and he is asking me to set him free. I have the option to do it but I can also kill him. I’m quite torn now on who to believe and what to do. I’d rather not side with him, but I feel like there might be some epic quest reward if I do. Based on the way this quest has gone so far, I feel like it might be worth my while to decide carefully.

For those who have completed the quest and made the decision on what to do, can I get some advice? Should I kill Lorenzo Cabot or let him free? What is the best option to go with in order to get the best Cabot mission rewards?

You have come to the point where you need to decide whether to kill or free Lorenzo Cabot. It’s tough when you are put in a position like this. Quite obviously that Lorenzo is a nut job, but what is the advantage of freeing him. Well here are the results of both decisions.

Should I Free Lorenzo Cabot

If you free Lorenzo you will get an infinite supply of the serum. You can only have one at a time, but if you keep going back to Lorenzo, he will continue to give you more of the serum. The serum will give you.

  • +5 STR
  • +50 Damage Resistance
  • -10 Radiation per second (lasts 3600 seconds)

The serum will essentially make you resistant to radiation for 3600 seconds and also make you pretty strong. If you think this will come in useful then, by all means, go for it as it can be very valuable to have this. In saying that there is also a perk that will make radiation heal you, so if you have 9 endurance this serum might not be worth it.

Should I Kill Lorenzo Cabot?

Killing Lorenzo is the morally sound choice to go with. If you don’t have much need for the serum then this is the option you should go for when faced with the decision to kill or free Lorenzo Cabot. The reward for killing him is the control of his “artifact”. This is actually just a gun, but its pretty cool. It is actually just a Gamma gun with some special mods on it. For those unfamiliar with the gamma gun, it shoots radiation at the enemy. This means it will only be effective against humans. The gun will also give a kickback which can be helpful.

This is a tough decision as the reward for killing him and freeing him are pretty even. It will be down to personal preference, which decision you decide to make, but at least now you know the outcome on whether to kill or free Lorenzo Cabot.


  1. There no more civil government.i going to let him leave.besides where w bathroom in cell.

  2. I know this is years later but definitely don’t kill him. The serum is so worth especially if you have the chemist perk. It’s basically unlimited +5 strength, 50 DMG resist and near unlimited rad resist and the serum lasts for 10-?? mins(with chemist perk). When it runs out go back and get it again.

    • Good tip. Gamma ray for just humans doesnt seem to be that wow.

    • I’m all for “5 years later replies” Just fyi. And I’m facing that decision again right now but forgot the plusses and minuses. It really is a great story arc.

  3. You get the zeta gun anyway after killing the Cabot’s it s on jacks body. So free him you get both things anyway
