These are old misconceptions that simply aren’t true. For one thing, the two boys weren’t “loners” as the two socialized regularly with friends.  Yes, they were passionate about playing Doom, particularly Eric.  You could say it was an obsessive hobby in that he coded levels to the game and really got into creating add-ons to it.  The two enjoyed playing it together and both got so good at it they would try and outdo one another.      Plenty of teens and adults play violent video games and don’t go off and kill people.  On the contrary, playing video games can be a form of cathartic stress relief and a way to take out frustrations and blow off steam.  It’s no different for these two that both had a lot of problems with their school.  But video games is not the catalyst of why they committed the massacre.  Playing video games obsessively is a symptom of a larger problem with these two. Playing these games were a way to feel like they were in control of their life because they knew the rules of the Doom world well (real life was far harder to master) and it was a way to feel like they had control over others. But violent video games did not hypnotize the two and give them the idea to go out and kill people.  Again, excessive video game playing is a symptom, not the main culprit. 

We can’t know for certain but I tend to feel Dylan never made any serious suicide attempts..save for only in his mind.  I explored a similar question before here. 

That sounds lovely and blissfully tranquil. And there’s no reason you can’t thank him. Just tell him. 😉 

It’s not real ‘footage’. You’re describing a scene from the film Zero Day.   There were no cameras in the library where Eric and Dylan committed the bulk of the massacre and no ‘footage’ of them committing suicide.   Columbine occurred on April 20, 1999, and the fictitious Zero Day ‘footage’ has a timestamp of May 1, 2000.  We have CCTV video of Eric and Dylan in the cafeteria only. See here and here.

Well, freak springtime snowstorms can and do happen in Colorado occasionally and the fact that it happened right after the massacre makes it a purely coincidental event. At least, that is how your average person would rationalize it. However, my feeling is that the weather was a kind of spiritual-prophetical reflection of this dark event that befell not only Littleton but the world and global consciousness. 

In a way, the boys even sort of willed or wished any sign of snow away so that they could carry out their destructive mission successfully.

The boys begin discussing how “fucking snow is gay” and that they “hope the shit clears out by Tuesday, actually Sunday.” Eric says he needs “dry weather for my fires.”

And they got their wish: clear skies, sunshine and warm weather on the morning of April the 20th.  The following day, as the victims’ bodies were processed by the crime scene investigators and taken from the building, the weather began to turn mercurial; the skies grew ominous and dark. The boys were last to leave the building. As they were carried out from Columbine, concealed by tents, a massive snowstorm began to fall unrelenting.  The boys kept the snow at bay until they had been physically extricated from the source of their discontent. It was like frozen tears of tragedy. The weather was once deceivingly nice and fair but in the blink of an eye, an icy cold storm fell like a sorrowful blanket on Littleton.  A wintery spell of darkness had begun, almost like a kind of curse with a ripple-effect which would burgeon others on in the name of it for many years to come.
