It was heart breaking for Bruce to learn the comprises Jim Gordon made with certain criminals namely Sofia Falcone. Losing hope in his father figure, losing the light he saw in other's and their darkness, in especially himself.. Bruce went after Hugo Strange's lab, gaining a serum for his possession.
Days after there were reports of a monster, something merciless tearing throughout Gotham leaving blood and rubble everywhere. Crushing, destroying, and ripping people apart. Seemingly intelligent, adapting and unkillable.
One ripping out parts of Ivy's garden, leaving her for dead. Stabbing Oswald, destroying one of his eyes with spikes, leaving Falcone comatose. Pure luck saved the infamous victims. They claimed it tossed them around, had spikes that grew and tore through his skin. That it made more burst out of the ground... Avoiding the Sirens Club completely, The GCPD was another matter.
You hunted it down, followed by others, GCPD, criminals working together to kill it . ... But just as you aimed a gun in it's face, isolated from everyone else it shifted, turning back into Bruce.
"When Jim lied to me, when he gave them freedom, a little reign over Gotham it hurt... I wanted to be strong enough, to harden myself even if it meant becoming inhuman changing me irreversibly..... When I became the monster I liked all the hurt, I caused, the damage. The blood. That was my fault.. And I don't regret it." You kept him away from everyone else as he explained... "
It horrified you, sickened you as the others grew closer. You could tell them, you could kill him in that moment.. Have him be locked away..
