Am I a good friend or bad person what is your opinion?

So me and my friends (6 of us) where hanging out in an ice cream shop (we are 19) then these two girls come in and one of my friends starts talking about how she looks good and stuff he would like to do to her. One of my friends told him to speak to her and get her number but he was too nervous and scarred.

I got up and went to them started talking to them and told the girl (the one my friend like) my friend likes you. She was hesitant she told me “if he likes me then why isn’t he the one speaking” I told her he was shy and don’t worry he is a good guy.

Eventually I got her number and set up a date for both of them, my friend was super happy.

I told my sisters of what I did (21,23) feeling proud, got my friend a date. They were not pleased with me telling me what I did was wrong and it’s deceiving to the girl.

They told me you did the work and she only said yes because of you so the date isn’t going to work for him and her.

I am confused what are they talking about it being deceiving?

Do you Y/A guys and girls think I was being a good friend or an interfering bad person?

What would your opinion be if I did that for you guys/girls. And imagine if you was in the girls shoe what would you think?
