bro it's kinda funny how everyone cared about Iruka when his parents died but when Kakashi's dad died barely anybody comforted him. What a strange world huh...
If I remember correctly, they say it was because Sakumo (Kakashi's dad) was a traitor, which is stupid since this is all because he prioritized his comrades over completing a mission. I find it shady, this village has more double standards than I can count the days on every month of the year. This village does not deserve any of the love and loyalty its shinobi poured into preserving it..
