Empirically speaking electrons are never seen without carrying a charge. This was then reified inductively into a universal principle that electrons are always charged and with the charge e.
The word 'carrying' or 'bearing' here is an artifact of language. In physical theory all electrons are alike and so it's part of the identity of an electron to carry that charge. In a sense, it is that charge.
Essentially, this notion comes from the theory of atomism where a fundamental or elementary element of reality is seen as universal: all atoms of a particular type are identical.
