Im still not totally sure he did it. Psychologically its easier to understand killers like Sutcliffe who are apparently motivated by a hatred of women.
But PR, while i can see he was confident and easy at the relatively low level of offences he was committing , i dont see the obvious psychological motivation to murder , it could have been an accident or simply a pragmatic choice in the circumstances he found himself in, a choice that he, given his assumed disfunctional mental state , was psychologicaly equipped to undertake and adapt to. Or maybe, in the way people of a certain mentality (psychopaths if you like) get an enjoyment out of torturing and inflicting pain on dumb animals, PR always had it in him and escalated from observing and stealing to hands on and murder.
That said , lots of people have psychopathic tendencies and dont kill , they are savvy enough to consider the consequences and are deterred , so its quite bizaare why PR would totally screw his life up like this. It dosnt logically make sense to me , i cant understand it. It would make more sense if he hadnt made it so easy for the police to trace him but he did it on cctv.
I mean whats his motive for murder ?
I don't think he set out to murder that night.
If he is guilty of the public penis flashing and the stealing of sex toys then I think he has simply got bored of these crimes and decided to step it up a bit.
There could be other crimes/assaults that he may be charged with yet too.
But it's not a big stretch to me that he has simply escalated from his flashing etc... to wanting to carry out an assault on someone and it went too far.
But I doubt his ultimate aim when he went out that night was to murder...think he would have built up to that eventually though.
All just my own opinion of course.
