What is this, murderer season?

[A Black Falcon]

People turn off their internal sensor that says "killing people is wrong" all the time, such as in war... I know this isn't that, but I was just saying that there could be another explanation. That they did it doesn't necessarily mean that they are insane, though I agree, it probably is pretty likely that they do have some mental problem or other that made this more likely... that is probable. It doesn't have to be flat-out insanity, though, I'd say.

Well maybe they were both unstable people who only managed to do this because through great fortune of events they found each other and could encourage each other's deranged whims.

Now that's possible. Yes. :)
