So just follow these rules and most likely your people will not commit suicide. The few people who have reduced murder impact is Roman, Emilia, Anton (usually doesn't care even when killing defenceless), and I don't know if this is true, but Bruno usually only cares about Bruno. So, tips for if you're going to kill anyone and don't want much or none at all, kill the bad people, if you kill bad people, don't kill only one 'KILL THEM ALL', (I've found out that if you have to kill multiple people at once or get a wound from them, most think 'self-defence' (Will only apply to bad people and soldiers about wound or killing multiple) ,but just one and the killer gets sad.) If they do get sad the best things to do are (make sad person drink alcohol, leave radio on a music station, make someone play the guitar, or help someone out). I gave her moonshine, still depressed, played radio on music stations, still didn't get over it, and she didn't get over it until she helped someone else. I got angry one night because some crazy guy wasted my time, so yeah, I straight-up killed him with a backstab. Boris was actually content in killing him, if there is one person I know that is really hard to get rid of sadness from killing someone is Zlata.

The supermarket anyone is fine if you kill the soldier because I've killed that drunk soldier before, with Boris, in the supermarket that tried to force the girl to. I only kill usually the bad people and you forgot a few other situations.
