I helped him kill his family. I'm glad.
So I was going through quest 'The Secret of Cabot House' and had sided with the Cabots, slain Lorenzo and was talking to Jack. Game crashed. So I reloaded and was back at moving through the security doors to get in to Lorenzo again. Now I don't save and reload based on dialogue choices. I do put a bit of thought into things and take what comes to me. But this time around I started to think about how I felt the first time through when It felt uneasy talking to the Cabots. When Jack told me to kill everyone no matter what and do exactly as he said.... that rubbed me wrong. So I went the other way.
In the end I think Lorenzo is a wacky character but there may be something to that artifact. ((Maybe we'll find out in a DLC but not sure how that would work for those that killed him. Suppose it just wouldn't focus on him.)) I'm glad that the second time around I realized that the Cabots were jerks using the man of the house to extend their lives indefinitely.
Anyone care to share what they did and why?
OH, what can I really use the serum for? Seems fairly useless.
