“Right - better she become a vegetable for the last few weeks of her life.”
And you know for a fact that would have happened? And what if it did? Does that mean her life has no meaning simply because you can’t see it? Isn’t more likely that you’re suffering from myopia?
“Just to make the people around her feel good.”
Feelings have nothing to do with it. Everyone will feel lousy no matter what.
“How does anyone know what was going on in her mind?”
She told us - on video no less.
“It’s easy to condemn her from others perspective.”
How about from God’s perspective? Does He condone suicide?
Since G-d created everything then He also created the tumor in her brain. You’re condemning her based on your belief system not hers. Maybe she decided to go see G-d and ask Him why? Ever thought of that? Your belief system demands she suffer.
