Watching Kruxe, did Alejandro plan on letting him go? No, but was he moved by Kruxe's tears? Yes.
Though a military man and a commander at that, Alejandro was a rather calm man.
Kidnapping citizens and torturing teenagers was not something he actively did, and so far in his life, this was a first for him.
Due to his initial feelings, Alejandro had been rather soft on Kruxe when he was found out, allowing the boy to be checked into the hospital.
With time though, Alejandro's frustrations grew and had decided to take this a bit more seriously with Kruxe, the man predicting that Kruxe would just be a dead end, but to his surprise, he found out that the young boy whom he had been merciful with and had actually been vouched for was very guilty.
