How to know if an entity is trying to cheat an entity or entities especially a competitor?

According to the council of God:

Philippians 2:3-4 KJV

[3] Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. [4] Look not every man on his own things, but every man also on the things of others.

1 Corinthians 9:16-27 KJV

[16] For though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the gospel! [17] For if I do this thing willingly, I have a reward: but if against my will, a dispensation of the gospel is committed unto me. [18] What is my reward then? Verily that, when I preach the gospel, I may make the gospel of Christ without charge, that I abuse not my power in the gospel. [19] For though I be free from all men, yet have I made myself servant unto all, that I might gain the more. [20] And unto the Jews I became as a Jew, that I might gain the Jews; to them that are under the law, as under the law, that I might gain them that are under the law; [21] To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law. [22] To the weak became I as weak, that I might gain the weak: I am made all things to all men, that I might by all means save some. [23] And this I do for the gospel's sake, that I might be partaker thereof with you. [24] Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. [25] And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible. [26] I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: [27] But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.

2 Timothy 2:1-16 KJV

[1] Thou therefore, my son, be strong in the grace that is in Christ Jesus. [2] And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also. [3] Thou therefore endure hardness, as a good soldier of Jesus Christ. [4] No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier. [5] And if a man also strive for masteries, yet is he not crowned, except he strive lawfully. [6] The husbandman that laboureth must be first partaker of the fruits. [7] Consider what I say; and the Lord give thee understanding in all things. [8] Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel: [9] Wherein I suffer trouble, as an evil doer, even unto bonds; but the word of God is not bound. [10] Therefore I endure all things for the elect's sakes, that they may also obtain the salvation which is in Christ Jesus with eternal glory. [11] It is a faithful saying: For if we be dead with him, we shall also live with him : [12] If we suffer, we shall also reign with him : if we deny him, he also will deny us: [13] If we believe not, yet he abideth faithful: he cannot deny himself. [14] Of these things put them in remembrance, charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers. [15] Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. [16] But shun profane and vain babblings: for they will increase unto more ungodliness.

James 4:6 KJV

[6] But he giveth more grace. Wherefore he saith, God resisteth the proud, but giveth grace unto the humble.

Because,

Romans 5:12-21 KJV

[12] Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: [13] (For until the law sin was in the world: but sin is not imputed when there is no law. [14] Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come. [15] But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many. [16] And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification. [17] For if by one man's offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.) [18] Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life. [19] For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous. [20] Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound: [21] That as sin hath reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord.
