Also, would make Malak a proper villain instead of Saturday morning cartoon one.
The funny thing is, the more you read about history and people, the more less cartoonish Malak appears. Stupid, yes, but not unrealistic anymore. There were enough men that thought burning and killing everything until the other side (ha!) gives up, is a legit tactic. Doesn't make Malaks portrait more interesting, just a more depressing.
Oh, glass-the-planet thing isn't cartoonish, but his delivery of, well, everything is. Things like "Mwahahahaha! Lady, imma gonna zap you until you turn eeeeevil! Muahahahahaha!!!" He even literally goes "Mwahahahahaha!!!!" at least once.
