Well... not really. He might be destructive and all, but he never killed anypony. If he was 100% evil he would have killed the ponies once he took the magic from them in Twilight's Kingdom (to make a comparison: Storm King was about to kill Twilight and Tempest, before the other Mane 6 intervened with that blast, or even Chrysalis when she took the mane 6 and the princesses to the hive, they would have died of starving and she wouldn't have cared anyway). This is something curious about Tirek: he's destructive, but he's not a murderer.... mh... [/bq]
He didn´t consider the Mane 6 a threat at this point.
I he knew that they had still a way to defeat him they would have been dead.
