Justice League Doom/Heartwarming

• Superman trying to talk a man out of committing suicide, telling him that "everybody matters", and that "you're stronger than you think you are". Sure, it was actually Metallo, and a trap, but it's still a truly heartwarming moment.
• Martian Manhunter's secret identity is blown when Ma'lefa'ak poisons him and sets him on fire. His human friends/co-workers rush to try and put him out, still calling him 'John' and 'buddy'.
• The ending, where, even after Batman's contingency plans nearly killed the entire League, Superman still trusts him with a kryptonite bullet, just in case Superman should ever go rogue.
• At the end, Batman decides to leave the League. Superman points out as he is preparing a teleporter that Batman didn't make a failsafe against himself going bad. Batman simply says, "I do have a plan. It's called the Justice League." While he may be paranoid and a bit hard to get along with, the Bat does trust his teammates with taking him down at least.
