Erzengel did his job, I blame the fuckface who reported the dude.
Guys like Chirs or Pepe, really disgust me.
The community should shun them and isolate them like they would do if they had plague.
If it is okay to ban him, it's also okay to report him. I don't know how you can draw the line there?
I don't know Alighar, and perhaps he is a nice guy, but if he is repeatedly TKing but doesn't learn anything, I think it's okay to apply the "learning through pain"-method as last resort. Every time he TKs someone he is spoiling someone's fun, and if he does it on a regular basis, he is spoiling the fun of many people on a regular basis, which seems enough of a reason for a 1 month ban.
Seriously, if I am in doubt I could hurt a teammate, I rather don't swing. I don't know how often I died because I was afraid of hurting team mates. When in doubt just don't attack. If you don't have that self discipline, then grow it. If you can't, our friendly admins will support you with bans until you have learned your lesson.
