What was the point of the last episode of Cowboy Bebop?

As one of the greatest anime of all time, there was one thing that kind of bothered me about the last episode. In episode 26, you finally see Julia. Up until that point, she was just referenced by the other characters of the show. Spike and Julia are finally reunited and decide to run away together to start a new life and put behind the sad and messy history with the red dragon gang. It was a plan that was deferred for three years.

Vicious ordered Julia to kill Spike or else Vicious would kill Julia. Instead of carrying out her orders, she went into hiding for three years. After 25 episodes, we finally got to see Spike and Julia together.

And things are going well until the couple gets ambushed in a bar and Julia gets gunned down and dies. It was tragic.

Afterwards, Spike goes back to the bebop to talk with Jet and Faye. After getting armed to the teeth with guns, C4, and concussion grenades he goes to infiltrate the red dragon headquarters. After taking out an onslaught of red dragon members, Spike has his final duel with Vicious and kills vicious while taking a mortal stab wound to the torso. Spike then exits the building to see the remaining red dragon members and then the falls to his death. It is one of the most moving and emotional scenes of anime history however I just can't get past how unnecessary it was.

After the bar shootout, Julia was already dead. Spike wasn't being pursued by the red dragon gang. He could have just left the planet and started a new life doing something else. As far as I'm considered, Spike went to kill dozens of red dragon members, blow up the headquarters, and kill Vicious all for .......... the lulz. Honestly, there was no reason to do any of that however I guess any other ending would not have been as moving or had such an impact.

Maybe Spike was motivated by revenge or maybe he felt that life just wasn't worth living without Julia but that just seems silly. Regardless, it is still the greatest anime of all time and I still do enjoy the ending. I just can't help but to think of how pointless it is.
