Sounds like this hope may be too late. While the obsession itself may not be a crime or damaging, the developing obsession you're describing can be. And this might also be a little concerning...

You can't equate the psycho- and sociopathic urges you've referenced here with a sexual addiction or a clothing fetish of any sort - and sympathising with those who express that degree of violence is either very naive or seriously misunderstood. Perhaps you didn't mean that the way that it came across...? Nonetheless, I also get the feeling there is an undercurrent of your ethnicity and culture in this too - a repressive environment is perhaps fuelling your need to rebel in any way you can...

Way too much going on here and probably more than we can see - yes, you need to speak to someone professional: Stat.
