point #2: Kaworu isn't necesarily a homosexual. (both anime and manga imply he's more or less completely ignorant of conventional sexuality, personal space and romance... while the manga gives him a clear set of "alternate" motives for hitting on Shinji in the first place)
point #3: Something tells me Shinji being hit on by that homosexual (at least in the anime) was the best thing that had happened to him in months, if not years. That would seem to imply that if Kaworu gets the homosexual label: Shinji should be sharing it.
And honestly, I don't think any of the three children's lives sucked half as much as everyone else seems to think. There certainly wasn't anything going against them that they couldn't have overcome mentally by simply refusing to wallow in their respective nuerosis and throw eternal "I'm all alone forever" pity parties for themselves.
All of them had chances to save themselves from their own bullshit. Only Rei actually did anything to take her life into her own hands, even if it was
I feel loads worse for Kaworu, Touji and Hikari. Largely because they actually TRIED to live their shitty lives, rather than hiding in the proverbial closet with their hands over their ears.
