She is brought to tears because she witnessed the magnitude of Erza's spirit and how wonderful a person she became growing up, and it would have been cruel to take that away.

Jellal's surprising backstory. His dad died when he was a little boy, forcing him to be the one to care for his mother and ensure her safety. Then, the Cult of Zeref sacked his home to take the children and murdered all the adults. He witnessed his mom get cut down, and then the cult took him prisoner. The kicker? "Jellal" is the name he chose to adopt after becoming a prisoner. His given name was Siegrain all along. Condemning himself for being too weak to save his mother, he believed that "Siegrain" would have been strong enough to keep his promise to his mom, enroll at a magic school, then get admitted to a more prestigious one in the city for his academic success, rack up many acheivements, then go on to join the Magic Council. This regret became the basis of the Siegrain identical twin persona that acted as his doppelganger, whose embellished background checked all these boxes. "Jellal" was really the falsehood he chose to live with in shame of being so useless.
