In my experience people plead guilty
a) because they are and actually feel regret.
b) because they do not have a choice, they will be found guilty regardless, so they want to appear to feel regret, so to get lighter consequences.
I should imagine anyone who pleads guilty to infecting someone, doesnt do so through conscience, if they had a conscience they wouldnt have deliberately infected someone in the first place.
The precendant has to be set somewhere, Courts are not allowed to just make it up.
The case was called R v Dica, and it took place in 2004.
"Mr Dica was told in December 1995 that he was HIV positive. He met the first complainant in 1997, and met the second complainant in 2000. Dica had unprotected sex with both of them. According to the first complainant, Dica actually insisted that they should not use protection, telling her that she could not become pregnant because he had had a vasectomy. During intercourse, he would also say ?Forgive me in the name of God?.
Dica was convicted at London Crown Court in 2003 of two offences of causing grievous bodily harm. The judge at the trial decided that the rule in the Clarence case was no longer valid in England and Wales, and Dica was sentenced to a total sentence of 8 years imprisonment. It had taken over a hundred years, but the English courts had finally come full circle.
When Dica?s conviction was upheld on appeal, the aptly named Lord Justice Judge made the following comment which is of particular interest to those with genital herpes and other ?less serious? STDs:
?In the present case we are directly concerned with HIV. However we understand that there have been significant recent increases in the recorded rates of syphilis and gonorrhoea, and that a significant proportion of sexually active young women, and many young men, are infected with chlamydia. Accordingly, although we agreed to accept submissions from the Terence Higgins Trust, the George House Trust and the National AIDS Trust in relation to HIV, and some of the problems faced by those with this condition, for which we are grateful, the issues which arise in this appeal are not confined to that devastating disease.?
In England and Wales, then, it seems as though transmitting any STD ? if you haven?t warned your partner ? can be considered a criminal offence"
