Unless you're the director on the movie, or putting up the money for the movie, you really don't have a lot of control.
If you just did a horror tone throughout an entire movie you almost, as an audience, can get a little bit used to it. But if you're laughing one minute and, you know, somebody's doing something quite horrific the next minute, it's a little more shocking.
After I got this job at the syndicate, I started sending them money so they could go on trips and do the things they could never afford to do. All the while, I never knew that my mother was socking money away.
