激しい is a common, everyday word for 'intense' or 'violent', but lacks the grand, heroic overtone that 壮絶 has.
壮絶 describes an intense, awe-inspiring struggle or scene without necessarily implying sadness, whereas 悲壮 specifically combines grief with bravery.
壮大 shares the kanji 壮 with 壮絶 but means 'grand, magnificent in scale' without any implication of fierce struggle.
Compound of 壮 (grand, robust) and 絶 (extreme, surpass). The combination conveys a sense of extreme grandeur or intensity.
