Caesar was assassinated because the Senate was jealous Caesar's wealth, power, prestige and love by the people. Also because he wanted to redistribute land, threatening their own power.
I don't think that is the consensus view of why Caesar was assassinated:
>...According to Suetonius, Caesar's assassination ultimately occurred primarily due to concerns that he wished to crown himself the king of Rome.[13] These concerns were exacerbated by the "three last straws" of 45 and 44 BC. In just a few months, Caesar had disrespected the Senate, removed People's Tribunes, and toyed with monarchy. By February, the conspiracy that caused his assassination was being born.
