I still struggle to find how bad her ME3 role is that so many people say it is. I would expect it out of non-Jack fans, but here, I don't get the outcry.
You're either giving Jack's character too little credit, or school teachers too much (or both). Teachers are not always perfect. They can be incompetent, unqualified, not likeable, among many other potential issues. I don't see why Jack wouldn't work out as a teacher for kids w/ biotics. She definitely has talent of her own, and teenagers sound like an age-group she'd relate to really well.
The problem isn't that she couldn't be a school teacher, but rather that she wouldn't. Its not about her being dependable or reckless, but more about what would the character actually do.
If you ask me, if Jack had the compullsion to help children she wouldn't be doing it as a teacher in an Alliance biotic camp. Jack is the type of person who --if she were inclined to-- would help out using the methods she knows to work.
I expected her to be attacking Batarian slavers that were kidnapping children in their sleep from colonies in the Terminus system. Stopping a new Cerberus Teltin facility before it was able to steal biotic new borns from maternity wards and turn them into weapons like they did to her. Even finding and saving one biotic child from an experimental facility run by Cerberus/SB/Alliance and helping him/her to find their way home while on the run.
Its not like she can claim that these children remind her of herself. None of them were kept in the condition she was in. She may be helping, but considering what she's been through it wouldn't have the effect as if she were helping someone(s) in a similarly perilous situation.
Its very clear to me that Jack's a character that has a strong wanderlust, a strong will and even if she's doing the right thing, she wouldn't do it by someone else's methods, which is what they wrote her doing. It just seems like they castrated her.
