Why are the kamikaze viewed as a crazy thing?

I don’t understand how it’s different than the UK sending soldiers to war knowing they were going to die and kill people. They are both dying for their country/empire. Is it just because of what they were fighting for? Like obviously the Japanese weren’t exactly the good guys. Like I’m not saying they were good I just don’t get why it’s seen as such an extreme thing when, to me, it sounds the same as sending any solider to war? Just a thought I’ve been having and maybe others can share their views
