While most people would say that Pete Doherty from The Libertines is a complete mess due to his impending heroin addiction, Doherty would blame guitarist Carl Barât for the fallout.
While Doherty was a drug, sex and rock'n'roll enthusiast, Barât was oftentimes violent and would also dabble in varying substances. Once, it got so bad Barât smashed his face on a marble sink repeatedly after an alcohol-infused night, and almost completely had his eye fall out.
The violence was too much for Doherty, and he even admitted that there was a time he was a "little afraid" of his bandmate. Eventually, the constant arguments and drunken spats were too much, and the band split up.
