Nope, you must use "a".
This is a veeeery, very complex topic, but for a start, the basic rule is that when the Direct Object is a person or an animal, you must use "a". Some examples:
Yo respeto A mi padre.
Yo respeto las reglas.
Ayer vi A María.
Ayer vi AL perro de mi vecino.
Ayer vi una casa preciosa.
You'll come across other rules and countless exceptions, so good luck with that!
