Linkin Park's lyrics for a long time were criticized for being "angsty" or "whiny" as if they were just complaining about something petty like "nobody understands me", but now people will realize just how dark and deep their lyrics actually were. Chester's lyrics were cries for help, but everyone ridiculed him and turned them into memes.
And just when we thought his demons were behind him during A Thousand Suns, One More Light really showed how they were still haunting him and never went away. I couldn't stand Heavy when it came out, but now I find it very beautiful and haunting in the wake of this tragic event. Chester was desperately crying for someone to reach out to him and no one cared. They just continued to make fun of him and "meme" him. They only care about him now that it's too late.
Also, I'm absolutely devastated knowing that I'll never get to see them live or meet Chester and tell him what an inspiration he was to me. I looked up to him not just as an incredible musician, but a role model. It kills me that my hero is gone and no one reached out to him when he needed them.
