This is the type of stories I would like to read here, give me more!
Here's one for you:
It turns out you can kill your son, leader of the Institute and also kill the leader of the Railroad. I tried to do both and wondered what would happen.
Nothing happens. You leave the institute and, unless I missed something, the game's just over. No more main quests on the quest screen, it's just over. It's like they wanted to imitate New Vegas's kill-faction-leaders thing but couldn't be bothered coming up with any consequences, so there are none.
Another classic, which I wish I'd screenshotted:
The Railroad want to incite a synth-vs-human race war at the Institute. Some science nerd has a plan to free the synths by hacking a door (?) or something, but the Railroad want the synths to violently break out. When you talk to the synth rebellion leader, you have four near-identical options, all of which incite the race war. There is absolutely no way to use the suggested nonviolent hacking plan.
Later, when you're assisting the synths, he asks if you have any objection to murdering some guards. The responses, paraphrased:
WHO ARE THE GUARDS? (this just takes you back to the other 3 options)
WANT TO FIGHT
NO PROBLEM
IF NECESSARY
Absolutely no way to refuse the quest or avoid killing the guards. It's hilarious.
