So here's my idea of what love means...where you sacrifice yourself to get your hands "dirty" for the ones you want to protect.
EXAMPLES:
Itachi- how he slaughtered his whole clan to keep Sasuke safe.
Batman- he takes the fall for Harvey's death in order for the criminals to stay locked up to prevent them from harming others.
I know this might be dorky but...Tarlok- from legend of korra how he took down his brother and himself at the finale. Whether it was to protect Noahtok(Amon) from going down that road even further or from preventing their blood lines passing down their blood bending, I dont know but I'd like to think it was both.
And I dont know if anyone whatches SVU(special victims unit) and there was this one eps. bout this pedo-step brother turning himself over to the poilice before he did anything and in the end he took his own life to protect any future victims. That really spoke to me.
So that's what this sketch is trying to depict, you can choose which scenerio. Whether you see that the guy got rid of himself to protect others, or maybe he took out his twin from hurting other or the twin himself.
