Gundam Seed was highly successful among fujoshits centring around the homoerotic conflict between Kira and Athrun, and thus Code Geass needed that kind of pandering too. Killing Suzaku was thus not an option from an economic point of view, which is imperative when it comes to shows like this.
>commanded him to live at all costs
>why didn't he just kill
Who, Euphie? You're stretching my man, that was clearly the result of a catastrophic fuck-up and definitely not what he meant to do
Besides, she wasn't even his friend. They met for like 5 minutes
>putting down a girl he met for not even one conversation that started gunning people down means he should have killed his childhood best friend
I think you genuinely might have autism anon, not much else can explain your lack of empathy
Are you fucking serious? You're saying a boy he spent a year with in his childhood, who is now trying to kill him is and ruin everything he worked to create, but killing his sister, whom he spent most of his childhood with and was in love with her, who tried to help him with his cause is no big deal? And you accuse me for lack of empathy? That's some fine hypocrisy right there.
