When i pass by people many people have intresting smells

Except one in particular. I have smelled it numerous occasions. And the smell is so awful i cant explain what it smells like. It smells worse than death. Like literally poison. I dont know if they know that they smell like that. It smells like what someone evil would smell like. I dont know if they actually smell that way or if i just smell their aurora. I have smelled it several times and it smells demonic. And i dont even believe in that stuff. I Literary want to stop and ask the person what they are wearing. Cuz im almost conviced that these people smell the way they do is because they are evil. It doesnt smell like trash. Or mildew. Or even dirty. But literally like evil black poison.
