If anyone reads my reviews, you will see that I was very unhappy with the depiction of Psylocke in the final issue of her limited series.  I am not going to spoil the ending but i AM going to ask...is there ever a good or right reason for the X-men to kill someone? Other then being outright attacked by them.

see current xforce  they are made for that specific reason and have active xmen as members that seek out constant threats and eliminate them under cykes orders

In the first issue of Psylocke's mini, Betsy casually offered to kill Sack....certainly wish she would've. What an awful name....Sack. He must've been well acquainted with the diabolical Taint, unless he was too "uptight".

Wolverine has probably killed thousands of people by now.  Mass murderer actually.  But the motive behind it was never just to hurt someone.  He's just a misunderstood person.  All he ever wanted was to be left alone, and he views the X Men has somewhat of a family.  But keep in mind now, Logan's family was really messed up.  So he doesn't trust anyone but himself....

" @CATMANEXE: But thats my point...his body and mind were damaged and he was no longer thinking straight.  Thats why assisted suicide is still illegal.  Even if he was begging and pleading for her to kill him, thats jsut all the more reason that she shouldnt because he clearly needed help...not to be killed...he did some terrible things to her but thats what i mean when i say they should be better.  She should have risen above all the terrible things he did and all the threats he was making and seen him for what he was: a broken man looking for an easy way out.  He shouldnt have been killed, he really should have been somehow incapacitated and given some sort of help...and if he got better and still wanted to come after her for not killing him then think what a great story that would have been. "

Don't forget that Matsu-o assisted in Revanche's suicide.  In a strange way, he's having part of her (Kwannon's body) aid in his own convoluted suicide. 
 
However, this wasn't assisted suicide.  It wasn't a terminally ill man.  Matsu'o may have been disfigured by Wolverine, but he was still essentially a strong men.  He had contrived events to lead to his death, but that isn't assisted suicide.  Yes, it is suicidal behaviour of him, but ultimately it's still murder.  A mercy killing?  Yes, but still murder nonetheless.
