On the other hand, Blake rarely helped people and when he did, it was usually for self-serving reasons. On the rare occasion, Blake may have helped someone, but usually it was a half-assed attempt because he didn't really care that much or because he had nothing better to do at the time. Blake never gave up a mission or delayed it just to help someone.
At the end of the day, when Blake genuinely cares about something, he lets no one and nothing stop him, he listens to no one, he lies, manipulates, threatens and bullies until he gets exactly what he wants and never ever gives up. So when any weak excuse stops him from carrying out something, it's because Blake barely cared, he was just going through the motions because it was expected of him.
There are 4 reasons why Blake helps people or appears to:
1) He has a use for them
2) They're people like him (vicious or violent fighters) so it serves his goals
3) He has more to gain from not killing them
4) He has a personal agenda that benefits himself
( Blake helps people because he cares...riiight )
