Is it ok for agencies to continue to debut idols that bullied in the past?

Our society needs to change. If perpetrators continue to do well, it's only victims that suffer. If they're not caught now and perpetrators continue to debut, this is going to become a common occurrence. 

1. [+1,155, -28] This is why it's important there isn't a precedent. Every time this happens, Hyunjin and Irene get mentioned but never once show their faces. Same goes for Kim Garam. We need to rectify this, even if it happens now. It's not right for a school bully like Garam to be active as an idol. Even Soojin got kicked from the group. Hyunjin and Irene aren't normal either. 
2. [+862, -3] The ba$tard fans that suck up to them are the real problem. 
3. [+815, -9] It's because fans still keep sucking up to them calling them "visuals" that they're still able to promote. So just because they're visuals, everything is forgiven? If things stay like this, just like Irene and Hyunjin, Garam is also going to turn out the same. In 6 months, Kim Garam is going to be dubbed 4th gen's "top visual." 
4. [+285, -0] It's quite scary we have such precedent and fans can say, "well X did it too, and they're promoting ok?" If this keeps happening, kids will think school violence isn't a big deal. 
5. [+232, -4] This is why Hyunjin fans are a joke ㅋㅋㅋㅋㅋㅋ If you've never engaged with his fans you won't know this but they're like Shincheonji cult ㅋㅋㅋㅋ. They keep insisting their oppa is innocent and didn't bully... ah, they're quite legendary ㅋㅋ.
6. [+202, -6] Lia is trying to cut the tail too, nothing about her bully case has been resolved either. 
7. [+46, -0] Don't even think about becoming a celebrity if you were a dirty bully in the past...
