if you are their good friends you should help them in starting good life and i am sure they will love this life too. We may have our beloved ones involved in crime and we do not want them to be hurt so in this case we can help them out of that crime not just support them. Allah will help them in getting rid of this bad practice. I pray for every gay and lesbians to get rid of this bad practice. They are human beings we should help them out not to leave them.
