Supported with Scripture is all sin looked at the same in the eyes of God or some worst than others ?
Throughout the old testament there are requirements for sacrifice for "sins of ignorance". A sin of ignorance is a sin one commits unknowingly or by accident. For example:
Lev 5:4 ‘Or if a person swears, speaking thoughtlessly with his lips to do evil or to do good, whatever it is that a man may pronounce by an oath, and he is unaware of it—when he realizes it, then he shall be guilty in any of these matters.
Lev 5:5 ‘And it shall be, when he is guilty in any of these matters, that he shall confess that he has sinned in that thing;
Lev 5:6 ‘and he shall bring his trespass offering to the LORD for his sin which he has committed, a female from the flock, a lamb or a kid of the goats as a sin offering. So the priest shall make atonement for him concerning his sin.
Note that while there is a sacrificial atonement for such sins, there is no sacrificial atonement for murder. Murder requires the death of the guilty. So yes, there is a difference in sins. See the writer of 1 John:
1Jo 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
He says that if say we have no sin, we lie. But later:
1Jo 3:6 Whoever abides in Him does not sin. Whoever sins has neither seen Him nor known Him.
There is the difference between minor sins and major sins. We all sin inadvertently, but not intentionally. Anyone who intentionally sins "has neither seen him nor known him". It's perhaps best illustrated in the Roman Church's teaching on mortal and venial sin. A mortal sin is a "sin unto death" while a venial sin is a "sin not unto death" as
@Xeno.of.athens pointed out above.
