AITA for telling my sister I'll give her $5,000 if she goes and gets an abortion?

So, I (F24) got pregnant with my first kid at 19. I didn't abort him because I knew that I wanted to be a mother and I didn't feel comfortable with abortion and I was in a stable situation and able to take care of my baby. The choice to keep my child was made well aware of the challenges and the provations I would be in. It made me work harder and achieve so much more than I could have done if I wasn't a mother and I never once blamed anyone for my situation or blamed god or whatever. And I never regretted bringing my child into the world as much as it was hard at times. My family gave me good support in the process and I was able to get a good job and live comfortably.<br><br><br>My younger sister (F20) is 4 months pregnant and she keeps complaining about how much stress and changes and fears she has. She's been saying she wasn't ready to become a mother. She keeps saying she was stupid for not getting an abortion. Our family have been pressuring her to keep the baby because they don't believe in abortion apparently even though they supported me when I chose to have my baby and they knew how much it costed me. But this time for some reason they blame my sister for her stupidity for not using protection and telling her she needed to live with the results of her mistakes. I was shocked at how indignant they were once they learned that she wanted to abort. They guilt tripped her so much I don't think she would be able to abort and was already telling people that she's keeping the baby.<br><br><br>She keeps coming to me telling me how scared she is about the future and the challenges and how she's not ready. I told her that I'm not going to stop her from anything she wants but I just want to make sure she's 100% aware and prepared as much as she thinks she is because it's not an easy journey to undo by myself. And I told her if I was in her situation I would have gotten an abortion without thinking but I'm not her and I do understand and respect her choice but to stop complaining and blaming the people around her because she made the choice. She said it was not her choice and that she was bullied into it. I told her she has the right to make another choice and that I'll support her if she chooses to abort and I gave her the money so she could pay for the bills and stuff. She was surprised and said she was scared to do it because she knows what our parents would do. I told her I'll give her the money and after she gets an abortion she'll give me back the money. And I'll be by her side and help her with everything and we'll just keep it a secret from everyone. I didn't want her to live her life being miserable raising a baby and blaming everyone for it because that's a horrible life for both her and her baby. I told her if she was brave enough to go through it I'll support her and everything will be okay.<br><br><br>My parents found out and were outraged and called me the devil and said the money was haram and they're going to ask for it back and pushed me too much and accused me of being an influence and trying to make a sinner out of my sister. I argued with them saying they should care more about my sister's well-being and if she's happy with the choice she made than influence her into something she's not happy with and make her live with regret but they said it was too late and what's done was done and she couldn't just kill a sinless baby. I'm mad at them and stuck to my side and I argued with them a lot and pointed out how much they changed into bullies. How I was in the same situation and they didn't act like that. I'm just mad and feeling angry and I want to know if I did anything wrong.
