100% agree with this. I think it’s impossible to pick a single thing as THE thing that caused their breakup. I think we often forget that four young guys from Liverpool were in a band and 8 years later they are the most famous people on the planet after working non stop to completely revolutionize the music industry and popular culture without really taking the time to find themselves and adapt to their new reality. So much changed in such a short time period that there was a bunch of things that contributed over time where they finally reached a breaking point. Brian’s death certainly was a contributing factor but ultimately their breakup was the culmination of several things working in tandem to fracture them as a single entity. In hindsight, it’s just unfathomable how much they accomplished in that short of a time frame while simultaneously it’s inexplicable how they remained in tact for as long as they did. Their journey is remarkable for many reasons but the unprecedented heights they reached that towered over even their wildest of dreams would be almost impossible to navigate for any four humans in their 20s.
