They wanted to show that Jodha wanted to end her life because not her husband or not her parents were with her, neither of them were supporting her.. But they could've explain it more nicely..
It's just my POV..
N one more thing, I thought that the sucide scene would be today but no that didn't happen...
Btw wasn't Jalal looking stunning when he was racing off to save HIS Jodha Begum?
