Having a central registerandasking relatives is mutually exclusive if the relatives can overrule the register.
I also feel very strongly about organ donation, but if I was in the position to donate my organs it would already be very traumatic for my children, and, in all honesty, if the process of donating my organs made things worse for them and they couldnt handle it, then their wishes, mental health, and ability to cope would be the factor that should be considered above all else.
If there was a central register and your child signed up to it, can you honestly say that you would be ok with showing up to the hospital and them already being in the theatre, and missing your chance to say goodbye to them?
It's easy to speak hypothetically, and talk about your wants when you're not the one who has to live with the consequences.
So we return to a central register that is consulted and that's and end to that. is too simplistic an idea.
I think signing up to a register, making your wishes clear to your family, and hoping that they abide by your wishes is probably about right. Most families do stick by the wishes of their loved ones, and the ones who can't would have huge emotional repercussions if they were forced into it.
Not wanting to donate your organs doesn't make you a 'selfish prick' at all.
The vast majority of us will not be in the position to donate anyway.
