Which anime actually have important characters die?

Gurren Lagann has one of its most prominent character died in the first half of the series, and similar thing also happened in most Getter Robo series.

Same goes with Madoka Magica, where some of its main casts also died throughout the series.

Several Gundam shows also had these kind of moments, like First Gundam, 0083, 00, AGE, and the infamous Iron-Blooded Orphans.

Some Macross series were also like this, where there are prominent characters that died in midway of the series.
