How is hatred between Orlando and Oliver transformed to love through forgiveness in As You Like It, and how can we relate this to today's situations?

In Act III, scene i, we learn that Duke Frederick wants
revenge against Orlando. He orders Oliver to seek out Orlando and return him to the
court. If Oliver fails, Frederick will dispossess him of everything he owns and be
prevented from earning a living in the kingdom. The last we see of Oliver until Act IV,
scene iii, is that he swears he never loved Orlando as he undertakes to obey the duke's
orders to find him:

OLIVER
O that your highness knew my
heart in this!
I never loved my brother in my
life.

When next he appears,
we learn how Oliver's hatred toward Orlando is transformed into love. In a flashback, he
tells Celia and Rosalind, as Aliena and Ganymede, with "this bloody napkin" in his hand,
how he encountered Orlando and how he was saved by Orlando from a hungry lioness in the
forest. Following their reunion, which was washed in purifying tears, "from the first to
last betwixt us two / Tears our recountments had most kindly bathed," Duke Senior
blessed their reunion and their mutual forgiveness of each other since their life and
death experience had transformed their hatred to love through courage and sacrifice
leading to forgiveness. Oliver says of "the gentle
duke":

[He]
gave me fresh array and entertainment,
Committing me unto my brother's
love;

Frankly, it's hard to
know how this example might relate to today's world-wide situation because the catalyst
for igniting love from Oliver toward Orlando and for reawakening early love from Orlando
toward Oliver was impending death under the claws of a hungry lioness, which led to
courage and self-sacrifice from Orlando. Previously, when Orlando first recognized
Oliver, after the snake slithered away from his throat, Orlando had no desire to aid
him.

It was a battle of moral conscience--which weighed the value of
human life in the face of danger against the value of animosity and enmity--that led to
Orlando's decision. A great impetus was needed for Orlando to choose on the side of
humanity and turn his back upon his personal perspective. From this, the supposition can
be suggested that without such life and death circumstances and such courage and
self-sacrifice, ingrained hatred cannot be cast out. The simple answer, however, is that
 Orlando and Oliver's situation applies today by showing that the battle of moral
conscience must give the victory to valuing humanity above valuing personal sentiment
and embitterment.
