You’re aware the House of Trade fire happened over 10 years ago right

And?

And if there’s any stories about Ukraine deliberately targeting civilians, please share

I take it you have never looked into it, as, among other cases, they literally struck a student dormitory and a civilian bus very recently.
Also, apart from the Ukrainian state targeting civilians, they have also very famously perfidiously used civilians/pretended military personnel to be civilians to carry out a drone strike last year.
