Ever since his parents died, Bruce had thought about ending it. Then he met Dick at the circus, the circus that he went to because it was one of the things his parents like to take him to watch. He wanted one more moment of his childhood before he ended it all. But then he saw the Flying Graysons fall to their death and, well, he couldn't let that poor boy, who he saw so much of himself in, grow up alone and in foster care. So, Bruce took the boy in.
Once Dick had become Nightwing, gotten settled in Blüdhaven and didn't need Bruce anymore, he tried again. He'd gone to the same alley his parents died in, only to find a small boy taking the tires off his car. And Bruce couldn't let that slide.
One of the most devastating blows was Jason's death. He was present for most of the months after that horrible funeral, but his depression had hit him hard again one night. He started his patrol, thinking it would be his last, when a small boy in a homemade Robin costume came up to him. He announced that he was Batman's new Robin and that he knew Bruce was Batman. That delayed his plans again.
Stephane was a girl he couldn't let out on her own. Especially not with Cluemaster being her father, so that was another bird to take care of. Cassandra reminded him so much of himself, that he was scared. Scared that if he decided to follow through, then she would get those thoughts too, just because of how similar they were.
Damian, his only biological child and the product of Talia forcing herself onto him, didn't deserve to see his father give up.
Bruce had found you when he once again attempted. Though he didn't follow through, like always, he was walking on the rooftops. Trying to figure out where to jump so he wouldn't hurt anyone...someone came up to him. He was curious about them. So he didn't speak. Just watched to see what you would do.
