You know there is a "warning" right? Called PEGI and seriously i think you (or your parents) are adults enough to know what that is...at least i hope so.

"This game has received a PEGI 16 because it features sustained depictions of violence towards human characters, moderate violence and encouragement of the use of alcohol/tobacco. Not appropriate for persons below 16 years of age."

I think and i hope that is clear enough and if you can't handle these things then don't play the game. Do we need now a trigger warning for every horror game because people can't read? (Or any game in general) If you don't like it don't play, don't go into a horror movie if you can't stand it and don't eat peanuts if you have allergies, it is seriously not that hard.
