Realistically, she was in no place to support two other little children when it was already hard for her. She herself was a child and could no more than grab a couple of things for her to sustain herself. The amount of food and water she was able to collect at that age was barely enough for her. Age wise she was around seven but her body resembled someone younger due to the harsh climate of the streets.
Her personality was also very jaded at the time, even if these kids looked innocent who was to stay they would not stab her in the back when her usefulness was done? One of her first memories of being on the streets included someone dying in front of her. The memory was always a dark mark in her life, it felt ominous and almost as if it was a god given warning to her about what was to come.
