Difficult, isn't it?
I suppose that ultimately, whether we find a person objectionable or not, if they've not been convicted of a crime then they're entitled to resume their life in whatever way they deem fit.
Paddy Jackson is playing in the Prem, having been found not guilty of rape. No reason why Yarde (not prosecuted) can't do the same. The Prem is full of blokes who have never been convicted of rape.
What if a hypothetical rugby player was convicted of rape, was locked up, released then went on to play professional rugby? Having served his time, there are no reasons why he can't play professional sport. I'm instictively uncomfortable with this idea, but he'd presumably be able to resume his job as a binman, so why not a rugby player? If you believe that serving a prison sentence is the punishment for a crime (or in rehabilitation), then it's horribly inconsistent to prevent anyone resuming their life after their sentence is complete.
With c. 400 blokes in the Prem, it's impossible to believe there isn't at least one wrong 'un.
