If you don’t know the full history of something, don’t make comments about it. Mustaine was the man with the attitude and especially drinking problem. The rest voted him out, not just James. Maybe you should not go on hearsay, but actually read what happened… it has been documented often enough, and acknowledged by both parties….
I’ve been a fan of both bands since approximately 1984. Both Mustaine and Hetfield have been self-destructive to their bands and yes, Mustaine was a bit out of control at the time he was in Metallica. But I also think Mustaine is a superior guitar player to Hetfield, although Hetfield is top 5 in metal as it is, and the more talented of the two. One thing that is clear, though, is that Mustaine has kept his heart in heavy metal and Hetfield is simply going through the motions.
