Everybody is a common man until someone provokes a serial killer lurking inside your deep dark soul . A killer who kills more than three persons is termed to be a serial killer . The minds of the serial killer might be bizarre, no one knows what goes on in his mind ….not even himself . These bizarre things inside his head might be due to his upbringing , his influence with the outer world or may be due to his sudden life changing experiences. During their childhood they are so vulnerable and attract many things inside their head this will reflect when they grow up . Basically Serial killers are categorized into two types- Organized & Unorganized.

Unorganized serial killers are those serial killers who don't have any pattern for killing nor do they have any kind of a  killing weapon . They kill people usually for cash or any ornaments . These killers have no intelligence or wat so ever and they tend to kill any victim who they find . They usually get caught very easily as they would have left behind N number of clues . Some of the examples are Auto shanker , Cyanide Mallika , Uma shankar . These people just killed their victims with only motive to rob them . They are mainly slum dwellers who have a rough childhood , whose father is a drunkard, whose mother is a prostitute or may be something else. These people usually have a very sad upbringing. 

 Organized serial killers on the other hand are those serial killers who have a pattern for their killing . For them Killing is like an art . Like how a painter admires his painting the same way they admire the way they kill . Some of the Organized killers are so educated and intelligent that they don't leave any clue behind and challenge the detectives to find them . One such Instance was Jack the ripper , Zodiac killer who used openly tell their victims to the media. Organized serial killers are such that they are so obsessed with their intelligence and art of killing and any one who triggers their art will be a victim himself. The only way to make them leave a clue is by mocking their intelligence or somehow finding their pattern or whereabouts which mocks their intelligence & by this they show anger and they might do a mistake and get caught . That happened with Ted Bundy . These killers use only one weapon to kill their victims . Ever heard of a person who killed people just because he was inspired by Dante's Painting. Yes u are right , The Red Dragon . 

To conclude this I just want to say that it all depends on the upbringing , if your kid shows any signs of autism or experience any bullying in school u might want to check on him .
